[Mailman-Developers] minor qrunner bug.

Just noticed a minor bug in qrunner. when qrunner starts up, it opens
the log files, and leaves them open.
this is fine -- except when the logs get rolled and restarted. When you
move the logs off and gzip them for storage, qrunner continues writing
to the (now unlinked) old files, not the new, zeroed ones. So all of the
qrunner stat and errror and whatever data from the time you roll the
logs until that instance of qrunner exits is gone (which, if you've
modified qrunner lifetime values, can become significant on a busy
Since mailman isn't oding much log processing, not a big deal. but for
sites that are (for instance) charging for list usage, or sites that
have implemented reporting, there are potential holes in the data, and
if they're busy so they have extended qrunner times, significant holes.
while open/write/close is expensive, given all of the other stuff
qrunner's doing and the relative lack of logging, I don't think it's
significant. Alternatively, it can notice the files have been
moved/zeroed, or perhaps accept a HUP like syslog...
