I discovered this the hard way, I did a run which generates much email 
and my p233-MMX desktop slowed to a crawl as it's load topped 15 :)

This may sound like an odd question but how where you using 
spamassassin? I have it configured using the spamass-milter plugin for 
sendmail (which uses spamc) and I get large load increases when heaps of 
mail is delivered. The milter also seems to slow sendmail down over time 
(the mail sever for a non-profit organisation I do stuff for has 
spammass-milter on it and while the load doesn't go up th time it takes 
sendmail to do stuff does). Given that you seem to have found a way 
remedy this situation I would be interested to know how.
