how to force a python service to reconfigure itself after updating?

[Larry Bates]

You could move the reading of the configuration
file inside the loop so it is read each time
the service wakes up.  Unless your configuration
file is huge (10,000+ lines), the overhead is
negligible.

The other alternative is to put a socket server
inside the service and have a small external
program to send something to it when it needs
to reread the config file.
