That's a real huge difference. Is this expected behaviour ?
I would say "no". I'm not sure what's going on, but I have a
suggestion for how you might debug it. To wit, run "sample" against
the process while it's consuming all the CPU and see where the CPU is
going. My guess is that the thread that CF creates to glue file
descriptors into the CFRunLoop has gone mad and is calling "select"
over and over again. If you can confirm that, we can start looking
at why.
