these issues, plus pid files, restarts, and uid changes.

Is it worth looking at this type of external solution?

I agree.

I think the argument against this is that there wouldnt be a way for=20
"daemonize python ZEO/start.py <options>" to check for bad options and ou=
tput=20
an error message to stdout. The options are checked after surrendering=20
stdout.

Apparently real people cant read error logs :-(
