I thought of a better way to handle the signal locking for cloned processes.
In the near future we are hoping to merge the two locks around process local
state (p_smutex, p_mutex) into a single lock. When that is done we could
make p_mutex a pointer to an seperately allocated and reference counted
lock, which could be shared among cloned processes acting as threads. So if
you acquire the lock on one process, you have acquired the lock on all of
its siblings. This would fix the concurrency issue.
