Comment 3 for bug 1987873

Took a quick look at this. I agree with removing the indefinite wait, but backlog processing will need to be tested, as with the proposed patch $from_network never changes value. Something like this might capture the intent better:

if ($msg) {
    # we just popped a message from the backlog queue
    # let's see if we can process it
    $from_network = 0;
} else {
    $msg = $self->{osrf_handle}->process($wait_time);
    if ($msg) $from_network = 1;
}
