I started making applications 15 years ago that started independent J
sessions to do special tasks working on data that was passed around.

I usually had some control files that other processes could check so
they would not interfere with other processes that needed to be
finished.

Most of the processes where started by scheduled services from the
operating system.

Quite often processes were running in parallel.

Some of the processes were sending data automatically between machines
and got and sent data to processes outside J.
