[Mongrel] Cluster restart leaving orphaned processes?

[cleaner416]

First off, a big thank you to Zed and the development team for  
mongrel and mongrel cluster.   I've deployed it for two apps (through  
an apache 2.2 proxy) and it's amazing how much snappier everything  
is.   Previously we were using lighttpd and lighttpd-fastcgi proxying  
through apache 2.0, which was turning into a hassle for lots of  
reasons, most notably the ruby fcgi bindings.   I was shocked at how  
easy everything was to get everything up and running with mongrel,  
and found the documentation to be just what I needed - not more or less.

My only question is this: when I run mongrel_rails cluster::restart  
or mongrel_rails cluster::stop/start the old processes do not get  
killed off and I have to do it manually.  I've noticed this on 3  
boxes, all running FC5 with user/group mongrel/mongrel.   Any ideas?

(Just as an aside, is there a gateway somewhere where I can search  
this list?)
