One more to thing to think about when daemonizing in python:

If your are using python logging and you want to continue using it after daemonizing, make sure to call close() on the handlers (particularly the file handlers).

If you don't do this the handler can still think it has files open, and your messages will simply disappear - in other words make sure the logger knows its files are closed!

This assumes when you daemonise you are closing ALL the open file descriptors indiscriminatingly - instead you could try closing all but the log files (but it's usually simpler to close all then reopen the ones you want).
