The accept mutex is a problem. Since there will only be one thread in the
accept_mutex,
that issue goes away. Instead, the workers are all sitting in a condition variable,
which we
simply broadcast a message for.

I don't understand why that could be an issue. For a non-graceful, just do the
following
in the signal thread
ap_clean_child_exit();
This attempts to clean up, and it kills off everything. Since the signal thread is
always the
original thread from the process, this should kill off all other threads as well.
