+%
+% \begin{function}{\sys_gzero_timer:}
+%   \begin{syntax}
+%     \cs{sys_gzero_timer:}
+%   \end{syntax}
+%   Resets the timer to zero.
+% \end{function}
+%
+% \begin{function}[EXP]{\sys_timer:}
+%   \begin{syntax}
+%     \cs{sys_timer:}
+%   \end{syntax}
+%   Expands to the current value of the engine's timer clock, a
+%   non-negative integer.  In engines without clock support this
+%   expands to $0$.
+% \end{function}
+%
+% \section{Benchmark}
+%
+% \begin{variable}{\g_benchmark_duration_target_fp}
+%   This variable controls roughly for how long \cs{benchmark:n} will
+%   repeat code to more accurately benchmark it.  The actual duration of
+%   one call to \cs{benchmark:n} typically lasts between half and twice
+%   \cs{g_benchmark_duration_target_fp} seconds, unless of course
+%   running the code only once already lasts longer than this.
+% \end{variable}
+%
+% \begin{variable}{\g_benchmark_time_fp, \g_benchmark_ops_fp}
+%   Functions such as \cs{benchmark:n} store the measured time in
+%   \cs{g_benchmark_time_fp} (in seconds).  Functions such as
+%   \cs{benchmark_normalized:n} store the estimated number of operations
+%   in \cs{g_benchmark_ops_fp}.
+% \end{variable}
+%
+% \begin{function}{\benchmark_display:, \benchmark_display_in_ops:}
+%   \begin{syntax}
+%     \cs{benchmark_display:}
+%   \end{syntax}
+%   Prints the time \cs{g_benchmark_time_fp} (in seconds) or the
+%   estimated number of operations \cs{g_benchmark_ops_fp} to the
+%   terminal.  These functions are called by functions such as
+%   \cs{benchmark:n} and can be redefined by the user.
+% \end{function}
+%
+% \begin{function}{\benchmark_once:n, \benchmark_once_in_ops:n, \benchmark_once_silent:n}
+%   \begin{syntax}
+%     \cs{benchmark_once:n} \Arg{code}
+%   \end{syntax}
+%   Measures the time taken by \TeX{} to run the \meta{code} once, sets
+%   \cs{g_benchmark_time_fp} and \cs{g_benchmark_ops_fp}, and calls
+%   \cs{benchmark_display:}.  The \meta{code} is run only once so the
+%   time may be quite inaccurate for fast code.  The
+%   \cs{benchmark_once_silent:n} function omits the call to
+%   \cs{benchmark_display:}, while \cs{benchmark_once_in_ops:n} calls
+%   \cs{benchmark_display_in_ops:} instead.
+% \end{function}
+%
+% \begin{function}{\benchmark:n, \benchmark_in_ops:n, \benchmark_silent:n}
+%   \begin{syntax}
+%     \cs{benchmark:n} \Arg{code}
+%   \end{syntax}
+%   Measures the time taken by \TeX{} to run the \meta{code}, sets
+%   \cs{g_benchmark_time_fp} and \cs{g_benchmark_ops_fp}, and calls
+%   \cs{benchmark_display:}.  The \meta{code} may be run many times and
+%   not within a group, thus code with side-effects may cause problems.
+%   The \cs{benchmark_silent:n} function omits the call to
+%   \cs{benchmark_display:}, while \cs{benchmark_in_ops:n} calls
+%   \cs{benchmark_display_in_ops:} instead.
+% \end{function}
+%
+% \begin{function}{\benchmark_tic:, \benchmark_toc:}
+%   \begin{syntax}
+%     \cs{benchmark_tic:} \meta{slow code} \cs{benchmark_toc:}
+%   \end{syntax}
+%   When it is not possible to run \cs{benchmark:n} (e.g., the code is
+%   part of the execution of a package which cannot be looped) the
+%   tic/toc commands can be used instead to time between two points in
+%   the code.  When executed, \cs{benchmark_tic:} will print a line to the
+%   terminal, and \cs{benchmark_toc:} will print a matching line with a
+%   time to indicate the duration between them in seconds.  Note that
+%   these commands can be nested.
+% \end{function}

+%   The main timing function. First time the user code once.  If that

+%   reasonable amount of time (this is to avoid division by a possibly

+%   times that can fit in one quarter of a second and measure that four
+%   times.  To save time we reuse the result of the first pass if
+%   \cs{g_@@_repeat_int} is one.  Once we have four results, find the smallest,
+%   divided by $65536$ and by the number of repetitions, and display that.
