As Aaron asked, it would be useful to strace the process to see what
exactly is waiting: mbox file or index files, dotlocking or fcntl

Maybe you could just try disabling fcntl locking for index files and see
how it works then:

lock_method = dotlock

Also if that doesn't help, try how mboxes work with only dotlocking:

mbox_read_locks = dotlock
mbox_write_locks = dotlock
