Want to try this with 0.99.10-test11? :) It now keeps the index file
opened for 10 seconds before really closing it, that should help with
the speed quite a lot. I just tested copying 4000 messages myself, I
didn't notice any actual increase in speed, but CPU usage dropped from a
few percent to 0.4%.

It still does a few unnecessary things every time mailbox is opened (ie.
at every APPEND command). I think I shouldn't try to mkdir() the cur,
new and tmp dirs immediately. Those could be more easily created if/when
stat() fails while syncing.
