POSIX CVs are supposed to support broadcast immediately before
destroy. What we have here is the waiting thread doing the
destruction, which is not guaranteed safe by POSIX, as far as I know.
Looking at, e.g.,
http://www.opengroup.org/onlinepubs/009695399/functions/pthread_cond_init.html
reveals that "It shall be safe to destroy an initialized condition
variable upon which no threads are currently blocked." Am I right in
understanding that the wait-destroy sequence should be quite safe this
way (provided no one else waits)?
