+ Wheel::Run does not reap child processes.  For that, you need to
+ register a SIGCHLD handler:
+ 
+   $kernel->sig(CHLD => "your_event");
+ 
+ The session will then receive your_event with details about $? when
+ the wheel's process exits and is reaped.  POE will reap child
+ processes as a side effect.
+ 
+ Another way to do it is to register $SIG{CHLD} = "IGNORE".  Use
+ sparingly and with caution: This may clobber a handler that POE has
+ already registered for SIGCHLD.  Why does IGNORE work this way?  See
+ the discussion in perldoc perlipc.
