Hmm, I'm wondering if the Cyrus devs would be receptive to the idea of  
implementing some dtrace probes in Cyrus.

Stuff such as mailbox open/close, IMAP operations such as SELECTs,  
message retrievals, and so on.

I run cyrus on my personal server now, so maybe I'll fool around with  
that idea.
