Only solution for now is to set /var/mail world-writable and sticky.

Another way would be to use more privileged process for handling lock
files. Some programs use setuid or setgid binary for that. I was
thinking that I'd let imap process request the locks from master
process. That would also allow overriding stale lock files created by
other users with shared mailboxes.
