Chris,
I don't dispute that. It's like shooting a machine gun through the path of a rotating prop... as long as the timing is right, there is no problem.

As for his claim "I haven't gotten an excess file in my logging directory", that is totally bogus. The extra files would be a side effect of what creates them, not what extension is used.
