OK, thanks. I'll add that to our (never ending) worklist.
Up to this point, we were not aware that we would have to make any
changes in any library routines. I have not looked at the libc clock
routine, but it sounds like I should take a look...
BTW, The SN platform does have a hi-res synchronized clock that can be
mmapped & read from user space. The clock is located in the "chipset"
and is synchronized across all nodes/FSBs.
