(OK, I'm *waaay* behind on -hackers.)

In  <20060221173357.GE71757@manor.msen.com> you write:

This looks very much like a bug I ran across a while ago.  Look for
"snapshots and innds" in the subject line.

It doesn't seem like this has been resolved.  You may slap my
hand for not filing a bug report previously; I'm about to do
that.

The solution, so far, seems to be "upgrade to 6.x".  Whee.

   Free time?  There's no such thing.  It just comes in varying prices...
