+    Revert "[glib/ucdn/icu/ft/ot] Make returned funcs inert"
+
+    This reverts commit 5daf3bd4494cce6b4fb074533be9e99c4d9e0edd.
+
+    If other atexit callbacks try to destruct the objects we destruct
+    in atexit callbacks, bad things will happen.
+
+    I'll come up with some other way to catch premature destruction
+    of HB-owned objects.
+
+    Fixes https://github.com/behdad/harfbuzz/issues/618
