--- Comment #3 from Iain Sandoe <iains at gcc dot gnu.org> ---
for platforms using pthreads as the underlying resource, then perhaps we can do
this without thread_atexit (which I do not see in many places) by using
pthread_cleanup_push ()

not sure if gthr.h abstracts that in any way (I do not have a patch at the
moment).
