Will you discuss it with me?  I've been looking at versions of 'once'
lately (ie boost's and my own) and would be interested in any problems
with pthread_once, as well as versions that don't use a mutex.  (Mine,
under Windows, appears to only need a Critical Section and a few Atomic
operations, which, I hope is slightly better than boost's version,
which uses a global named mutex...)
