60 seconds is also when Dovecot decides the dotlock file is stale. So I
guess the cache file compression is taking longer than that. Hmm. I
hadn't thought about that before, since it was supposed to happen rarely
enough. But I guess during the compression other processes shouldn't be
stuck waiting for it. I'll have to think about something - probably make
the lock timeout only a couple of seconds and after that just fail to
update it.

But the cache compression really shouldn't take that long unless you're
really really running out of disk I/O. I wonder if there's some problems
with the locking / NFS caching. You do have mail_nfs_*=yes, right?
