Re: session_write_close()

To launch a background process within a session, I recommend
to use a start-stop-daemon and ship parameters via ENV.

Example:
----------------------------------------
<?php
  // Within a session..
  exec("/some/where/launch.sh 300");
  // ..finished immediately.
?>

----------------------------------------
#!/bin/bash
# /some/where/launch.sh
T=$1
export T
DAEMON=/some/where/runme.pl
start-stop-daemon --start --quiet --background --exec $DAEMON

----------------------------------------
#!/usr/bin/perl
# /some/where/runme.pl
my $t = $ENV{'T'};
sleep($t);

----------------------------------------
