FYI:Popfile.pl is a big cause of wakeups

Just thought I would highlight PopFile.

Popfile, the spam mail scanner, causes wakeups at the rate of 20 per second.

It is caused by a select() statement in Loader.pm, which sleeps for a  
measly 0.05 seconds between polls.

I have found popfile works quite satisfactorily if I set the sleep to  
0.5 - and would probably be just fine with an even longer sleep -  
after all, how often do we retrieve e-mail and I guess that a longer  
sleep would only delay mail retrieval by, at most, that amount.
