I'll look at that. I gotta think about how to coördinate the child processes and get data to/from them. But it looks good if I can understand how threads are different than processes :).

Just to experiment, I tried fork()/wait() because I'm familiar with that. I wrote a little test program to see if the forked children were running and I got: 

>parallel
this is a test of parallel processing
Starting the first child
first child pid is -14236
I'm the first child and I'm gonna wait for a while
second child pid is -10372
I'm the second child and I'm gonna wait for a while
number 1 signing off
number 1 is done
number 2 signing off
number 2 is done
we're done

but I haven't a clue about the negative process IDs {and, indeed, I looked at task manager and there wasn't either process in the list}, so I couldn't tell if they were really independent processes and would run on different CPU cores.

Back in my Unix days I wrote a complete TCP server in Perl! worked like a champ. Sucks that Windows doesn't have a fork/kill/wait process structure} so it looks like i have a lot of learning to do to get something like that to work on Win10.

Thanks!
