swift/account/reaper.py 110 has reference to self.reap_once()
swift/account/reaper.py 119 has reference to reap_forever
swift/common/db_replicator.py 435 has reference to self.replicate_once()

review: Needs Fixing

oops... thanks for catching that, should be fixed now

Hi! You may want to use the existing daemon Python library instead of rewriting that stuff ;)

http://pypi.python.org/pypi/python-daemon/

Also, a litte nit: the standard way of passing options for daemonizing a process is not to pass "once" as a CLI arg, but to use CLI options, such as --nodaemon

Hey Jay, The main purpose of this was to refactor what we have currently to be more DRY. I'm not against moving to a standard lib for doing the daemon stuff, but don't have time to evaulate them. And as to the CLI args, I would like for those to change eventually as well, but that requires other changes as well, and was trying to keep the changes as minimal as possible.

Thanks Chuck!
