Good! When I just checked I thought I'd found a new hanging pop3d process, 
because it's been around for 6 hours, but in fact it's still working:

Sigh. But that's beside the matter. The only other potential downside the 
patch has is that stracing or gdb'ing it causes the timeout to trigger 
prematurely. AFAIK that's a common issue for signals. I'm not sure if 
there's something that could be done about that, i.e. catching ERESTART or 
something like that?
