That sounds like a bad idea. Long before you've run an infinite number
of processes, a real resource will be exhausted.

Yes, each time the process is created, it remains.
os.waitpid(-1, os.WNOHANG) doesn't work before starting the process
for the first time.
I tried this:
pid = os.fork()

There is a script running continuously which executes an external

After several hundred executions (cycles of the loop), the main script
gets an exception while trying to start the process. This situation is
