Summary: Use inotify instead of polling in Runner.py
Initial Comment:
Hi,
the Mailman wakes up 7 times per second which is somehow resource unfriendly. This is caused by qrunners that poll for new files in queue directory. The proposed patch replaces polling in Runner.py with inotify which enables CPU to idle when possible.
The patch requires python-inotify (http://pyinotify.sourceforge.net) to be installed.

Yes, you're right... I didn't realize that inotify is Linux specific. I
will add a configure script option -- this should solve the Linux-only
problem and make the python-inotify dependency optional. Also I will take
a look at Mailman 3 and try to create a patch for it as well.

IIUC, inotify is a Linux-only thing so this would have to be optional. I
haven't looked at the patch, but I would target this for Mailman 3 instead
of 2.2.
