Thanks for the tip. Using gdb was exactly what I needed (I've never used it
before, neat). I was using two url_regex acls, and the regular expressions
I was using seem to be the problem. Removing those two lines dropped CPU
usage from a low of %50 to a HIGH of 10%. Yikes. Off to optimize them.

Once again Henrik, you are a savior.
