  Log:
  Convert the lwp list into a red-black tree.  This greatly reduces the
  overhead of looking up LWPs for numerous operations including select and
  removes the hokey fork code that tried to avoid doing a list traversal.
  
  One inefficiency remains which cannot be easily fixed, and may not matter
  much anyway, and that is delivering a generic signal the process may have
  to iterate through many LWPs before finding one that can handle the signal.
