There was a bug that caused a panic if quotas were changed for a user
who had recently deleted a file (users logged in, or who have recently
been logged in, usually delete quite a few files...).  I suspect this
is the bug referred to.  I will post the fix to net.bugs.4bsd.
(The panic this caused was "maknode: dquot", or "mkdir: dquot".)
