I don't actually understand why UW imapd doesn't allow it. It needs to
be able to deal with unexpected mbox changes anyway, so why allow only
one IMAP session for it? Or maybe it deals with unexpected changes just
by killing the IMAP connection? I'd have to try some day.

Few days ago I was also wondering how UW imapd even knows how to kill
the older connection. It seems that it writes PID to
/tmp/.<device>.<inode>. When another IMAP process tries to access the
same mbox it sees the file, sends SIGUSR2 to the PID inside it and waits
for a while to see if the lock file goes away. Strange.
