No, it predates even those.  I've had this on and off for 6 months on some
of my machines.  If phk has done anything, I strongly suspect he's merely
just irritated some already-lurking bug.  Last time I looked at it, it looked
as though the MNT_RELOAD was getting lost or ignored or never issued.

I'd like folks to try something for me..  When this happens next time and
fsck reports the fs is 'clean' but mount says it's dirty, try a 'tunefs
-n disable /' (which forces a MNT_RELOAD) and see if you can then mount it.
It's fixed it for me in every case that I've seen so far.

Anyway, it was sporadic.  Sometimes it happened, sometimes it didn't.

Cheers,
-Peter
