I would say that this should be the default behavior:

If the signal is SIGTERM and the service is configured to restart the
program, then restart the program.

So, --neverxits should be the default behaviour of cygrunsrv , so
--neverexists shouldn't exist as an option. :) But perhaps I'm wrong
and I don't understand completely the problem.

Thanks for your time.
