no, I don't think so anymore :)

Because we have to connect() to the server enough times to wake up
each thread (ap_daemons_limit * ap_threads_per_child for the threaded
MPM), we will end up writing that many '!' characters anyway so there
is no harm in more than one thread in a process consuming a char from
the pod.  There are plenty to go around.

The old pod support unique to threaded only wrote to the pod once per
process so it had to ensure that no more than one thread per process
would consume a character.
