Bugfix: asynchronous processes not executing properly according to dependencies.

Bugfix: asynchronous processes not executing properly according to dependencies.

The controller_process_wait() function is returning immediately because the status is being changed and is only checking for F_time.

Add status_lock to separate it from status.
Return if status is an error.

Require Rule status to be both not F_known_not and not one of "active" or "busy".

If processes are waiting for a while and a signal is received, decrease the wait timer.
