Current python got pretty whiny about regex stuff....
Try something like this from the patch I did for my rtldavis consolidation
of Luc's code there. Same problem.
IDENTIFIER = re.compile(*r*"^\d\d:\d\d:\d\d.[\d]{6}
[0-9A-F][0-7][0-9A-F]{14}")
See the the r character outside the outer parens within the ( ) ????
Try that and see if it quiets down.
