                 I'll list some of the problems I'm seeing in case someone
                 else wants to pick up where I've left off:
  -               - The parent process goes into a loop consuming lots of CPU.
  -                 It has to do with how waitpid() and apr_sleep() are called
  -                 from within server_main_loop(). ktrace/kdump output shows
  -                 some weird stuff happening with poll() and suspiciously
  -                 small timeout values (apr_sleep() is implemented with
  -                 select() which is implemented with poll()).
                  - Delivery of just about any signal to one of the child
                    processes will send it into an infinite loop as well.
                  - Even though the parent is spinning out of control,

                      those decrementing select calls have to do with the 
                      scheduler.  Time to brush up on our OS fundamentals.

  -      David says:  Having spent a fair bit of time tracking this further, it
  -                   seems that FreeBSD's thread_kern_poll gets into a situation
  -                   where it polls for the kern_pipe and gets a hit (so the
  -                   timeout becomes an irrelevancy) but the pipe never seems to
  -                   be read and so successive calls simply return and the cpu
  -                   usage grows. Time to flag this to the FreeBSD team.
   
       * There is increasing demand from module writers for an API
         that will allow them to control the server  la apachectl.

  +  *) Fix the main bug for FreeBSD and threaded MPM's. There are
  +     still issues (see STATUS) but at least the server will now
  +     run without crashing the machine.
