Brian Barrett dfdb5dc12a * high resolution, low latency timers for a number of platforms, plus mods
to opal_progress() to use the timers instead of a tick count for deciding
  whether to call the event loop or not.  Currently supported platforms are:

     - solaris (x86 / sparc)
     - Linux (x86 / x86_64 / IA64)
     - Mac OS X (x86 / Power PC)
