Apache::Session doc says it dies if it can't update
the session. Are you catching that die somewhere
without realizing it? Determine if update is
attempted and fails or not attempted at all.
Try undefing the session (undef %session; # -- who
says perl is cryptic ? ) as soon as you are done with
it . "This will free up any locks associated with your
process" [docs]
