Well, when index is up-to-date it's fast. But after you've received a
few mails, at least with me it seemed to spend more time updating the
index than just doing the regular search.

Looks like there's something very wrong with mbox with v1.2+. It's doing
a *lot* of message header parsing work that doesn't happen with v1.1 or
with other mailbox formats. Probably because I fixed some bugs where it
was wrongly caching some state, but now it's not caching it long enough.
