Your timing is impeccable.  I've been having an issue with mongrel  
processes inexplicably dying recently and, while I want to get to the  
root of the problem, this is a great interim fix.  Now I just get an  
email saying that the process has disappeared and my faithful  
employee has kindly restarted it.  Thanks!

As to why the mongrels are dying, well, it's a mixture of crashes:

so that's going to be ... fun. :-/

Cheers,
