Yeah, we need to lock DB files but we don't need to lock mailboxes.
I removed/added message files in a Maildir while hcache-mutt was opening
the Maildir, and no failure happened.

So, Thomas(TLR), you no longer have any reason to dislike header-cache? ;)



For DB4, sleepycat document says we can even use concurrent access mode
although this seems not NFS-safe...
        ( http://www.sleepycat.com/docs/ref/cam/intro.html )
And I've just found DB_LOG_AUTOREMOVE mode
        ( 
http://www.sleepycat.com/docs/api_c/env_set_flags.html#DB_LOG_AUTOREMOVE )
which seems to keep db file small in size.
Are there any DB4 guru to improve the patch?
(Although I'm satisfied with the current patch. :)
