Add a sig_chld( $pid => ... )
This would register a handler to dispatch the SIGCHLD for specific PIDS
to specific events or callbacks, instead of sending ALL to it.
As each PID's sig was dispatched, it would remove that PID from the
outstanding list.
Once all were dispatched, it would automatically remove itself.
This would help let ::Wheel::Run do all sorts of more interesting magic,
and greatly simplify the writing of child handlers.
