I run mine at gc_probability = 5 instead of 1, but on any reasonably busy
machine it shouldn't really matter.

Also, I hope I explained clearly what I meant by "active" sessions.  In my
terminology a non "active" session is not (necessarily) one that should be
garbage collected.  An "active" session is one that corresponds to a
currently logged in user.  A non "active" session is one that corresponds
to a user that has logged out (or has not logged in yet) but still has a
valid PHP session.
