Hmmm ... never seen this.
If you try to do something like a "ls" in that directory, do you get
any errors? Timeout?

No, Maildirs are designed to work without locking.
See
$ man 5 maildir
and there the [RELIABILITY ISSUES] section:
[ ... ] In contrast, in maildir, no locks are ever necessary.
[ ... ] maildir works without trouble over NFS
qmail-pop3d doesn't use locking either and there is no prevention for
simultaneous access to the same Mailbox.
In FreeBSD a lot of NFS bugs have been fixed since the 3.2 Release and
- from my feeling, no facts ;-) - it has become more stable and reliable.
