I agree that it was broken before, but the shutdown and restart most likely
won't work anymore.  Someplace, we have to have the status of the listener
thread.  Before this patch, the parent process could always tell what the 
child was doing by looking at scoreboard[0].  We can't do that anymore.

I should have documented that, but I didn't.  This MPM is much better than it
used to be, but it still needs some work.  I am not suggesting backing out
this change, just wanted to make people aware that there is still work
needed on this MPM.
