I would appreciate that very much.

I'll include my thoughts in case they help:
What about a daemon signalling a waiting perl script? The script would
wake up, take the first file, process it, repeat until no more files, then go
back to sleep.
Is it an issue if the daemon signals the perl script when it's already
processing? Could a signal be missed?
thank you.
