pthread_atfork() does not fork, it does something entirely different.
Read the man page before suggesting we use it :-)

However, you have raised a very valid point... we cannot use
pthread-related functions for synchronization after forking, because we
are not running in the same process any longer. I will have someone look
into this, thanks for raising the issue!
