What stats would you like it to log that it doesn't already?
There's no communication between the child processes once they are 
started, but I could add a signal trap so that a kill -USR or something 
would make them dump some figures to some file or other, then restart 
the batch they were on. They already catch kill -HUP to force them to 
die. So exactly what do you want to do when it receives a SIGUSR?
