Hello Chris, 

Ok, makes sense.

I tried having the child create its own DB connection (object)
which seems to work all right, until it executes the query,
at which point it says the DB is gone.

I'm trying something a bit different now, using two files, parent
and child and then using the queue to send messages back in forth,
such as, the childs PID (so the parent could kill it if it runs to long)
and the return value of the child (success of failure).

This way eliminates the fork and the reaping, as the child's just exit(0)
when they are done, or worse (haven't coded this yet), the parent can 
kill them (since it tracks the pids and job_ids).

Truthfully, I dont know what the easiest way to do this is, nor 
can I find any good documentation on IPC and php.
