Faster? How large mailboxes or slow computer do you have? :) I don't
think I made it any faster, and I don't think it was slow before
either.. It took more memory though.

flock? With maildir? There's no locks with maildir, except for
uidlist.lock file which relies on O_EXCL working for open(). Indexes and
others are locked with fcntl(), unless you've directly changed that from
sources.

But I'm not really sure why the above happens.. Even the crash shouldn't
happen if the corruption happens (I forced corruption, worked fine). It
would help if you could get gdb backtrace, core dumps can be enabled by
setting "mail_drop_priv_before_exec = yes" in config file.
