Sure, but now I'm not sure what your point is here.  Are you suggesting
a gcc-C solution using a lock struct?  I don't think that a bad way to
do it, but it much more involved that the "defer" example that was
posted.

My point is the gcc's "cleanup" does not seem to be quite up to the task
in the way that the proposed "defer" is.  You appeared to be saying that
it was only some details that separated them, but that might be down to
what constitutes a detail for you.
