Thanks for the explanation.  I had understood phplib's "GC" to
mean "delete from the table sessions that are expired", as opposed
to "check all sessions which should be expired by now, and expire them"
(which is how I'm interpreting your message).   Sure enough, since
this is an experimental horde/imp that I set up, nobody else will
go around and GC very often.

But wait, something else just ocurred to me:  If the browser was
left open with the horde/imp session left on, won't the "auto check
for mail every xxxx seconds" facility essentially keep the session
alive, since it really _does_ access it every so often?  If this is
the case, that will explain why it's "still active".

Then I guess we'll see it gone in the next release :-)

Again, thanks for pointing out these things.
