Before we find out why the transactions are not freed on time, I would
like to run a test every minute that checks if the shm usage is too
high and, if so, executes tm.clean.  Something like this:

route [every_minute] {
    $var(shm_usage) = ($stat(real_used_size) * 100) / $stat(total_size);
    if ($var(shm_usage) > 90) t_clean();
}

Otherwise OK, but there is no t_clean() function.  Could that be added?
