Summary:                    Asterisk consumes 100% of CPU on Mac OS X
Description: 
I've run Asterisk 1.8.0 and 1.8.1 on several Macs (all running Mac OS X
10.6.5) and in every case it sucks up 100.x% of available CPU.  (Note that
in call cases the system has at least 2 cores, so this is possible).  I've
run a profile (or what the Mac calls a "sample") and it shows a lot of
this:

    2169 Thread_29623
      2169 thread_start
        2169 _pthread_start
          2169 dummy_start
            2169 do_devstate_changes
              2169 _pthread_cond_wait
                2169 __semwait_signal
    2169 Thread_29624
      2169 thread_start
        2169 _pthread_start
          2169 dummy_start
            2169 tps_processing_function
              2169 _pthread_cond_wait
                2169 __semwait_signal
    2169 Thread_29625
      2169 thread_start
        2169 _pthread_start
          2169 dummy_start
            2169 do_parking_thread
              2169 ast_internal_poll
                2169 select$DARWIN_EXTSN

I'll attach the complete sample file.  Please let me know what else you
need to help figure this out.
