A minor irritation with GoServe is that if it detects an error
while running a Rexx script, it will abort. We get round this by running
it inside a command file provided by Mike Cowlishaw, which runs it inside
a do forever loop, waiting a bit and then restarting if it crashes.
In case the process running this file itself should terminate for any
reason, we have another level of protection, namely a Cron demon which
runs through the list of process names checking for the name of this
command file, and which restarts it if it can't be found.
