I would also like to avoid this in general, but we have many
subprocesses to launch and some of them might take weeks, so we need
to have a process which is always running, because there is never a
point in time where we can just say let's stop everything and start again..

Anyway if there are better solutions I'm still glad to hear them, but
I would also like to keep it simple..

Another thing which now we need to figure out is how to communicate
with the live process..  For example we might want to submit something
manually, which should pass from the main process.

The first idea is to have a separate process that opens a socket and
listens for data on a local port, with a defined protocol.

Then the main process can parse these commands and run them.
Are there easier ways otherwise?
