[Twisted-Python] log.callWithLogger not used - slows down reactor?

I'm hunting down performance issue in our code and spotted this in passing. As far I can tell nothing seems to need callWithLogger. I ran our 6k+ tests with this patch applied and everything worked. Does anything in the twisted world need it? Barry diff --git a/src/twisted/internet/pollreactor.
