From the $job object (obtainable by sending a callback
to visit_all_jobs()).  Though actually, it looks like using
$job->{pathqueue} instead of the datapath might be easier,
so that pickup_queued_job() doesn't have to read the
queuefile (to find out the datapath).

Okay, I've attached one.

thanks!

ps On a separate note, I noticed that read_control_file() is always
called with two arguments, but the second argument is ignored.  Is
this perhaps an alternative to saying 'local *IN' in read_control_file()?
