Summary: TimedRotatingFileHandler's doRollover opens file in "w" mode

Initial Comment:
if TimedRotatingFileHandler does an doRollover() it opens the new file 
hardcoded with mode "w" whilst the baseclass FileHandler opens it with mode "a" 
if nothing else is specified in the constructor. it should use the same default 
behavior as FileHandler and/or give a way to specify another open-mode.

if multiple processes write to the same file, and one does the RollOver all 
other newly spawned processes write to the end of the new file but the still 
running first process who did the rollover will write from the beginning of the 
file - overwriting log entries from the other procs...

This sounds like a logging module issue.
