[imp] /tmp directory not being purged of session files.

Andy -

You were clear. And I understood what you meant.

This is a problem that I am observing (with garbage collection) in
PHP 4.2.3. ( I recently upgraded from 4.2-dev to be able to use
php_accelerator).   But, I currently see files in the /tmp/session
dir that contain active session information which are older than
gc_maxlifetime.  

To test,  I increased gc_probability, to 3, then 5, then 25.  It
still didn't clean up the session files.  When I did a ls -l on the
/tmp/session dir, I saw files that were old, really old --hours old. 
My gc_maxlifetime = 3600 in php.ini.  I confirmed these settings by
<? phpinfo() ?> .

I noticed this because my MRTG graph kept increasing, instead of
indicating a relatively steady number of logins.

I filled a bug report with PHP.net.  I have been asked to upgrade to
the latest SNAP version, and check again, which I am in process of
doing.
