Does reverting this change also fix it for you? http://hg.dovecot.org/dovecot-2.1/rev/6c1b4b9f527c

I guess you're using only LMTP to deliver mails? How many CPU cores do you have?

Also how much is "a lot", especially compared to the number of users you have / emails you get? I think it didn't happen very often for Morten (something like 1 error per several tens of thousands of mails?)
