I got loads of up to 60 when i used exim with Mailman 1.1 ... and
then slowly the system started to die ... this was happening when sending
about 20 approved posts to 1500+ users. I configured exim not to send
out anything when getting a higher load than 5, but then my fcgi scripts
would die anyway during posting approvals...
Since i'm using postfix with MM 1.2, loads don't get any higher than
2 or 3. So i'm very happy with the changes in 1.2 :)
