Because KISS

The design in the OP gives two very disparate jobs to the 'Boss'. It must flip between checking if there are results on the results queue and handling them, then seeing if there is anything to read on <STDIN> and passing it off to workers. The OP is talking about using non blocking calls and sleeps to do this. The complexity clearly recognised by the multiplicity of punctuation marks ... Monitor $RXQUEUE and <STDIN> - simultaneously???

If we split these two functions then we have two simple tasks.

both tasks can be written with blocking calls ensuring they sleep efficiently until they have work, then spring to work with alacrity when there is something to do.

Cheers,
R.
