The company i work for makes high performance interconnect solutions
for super computers.  i'm working on a demo where we're sending data
around a ring and i wanted to timestamp all the packets as it hits
each node of the ring.  the servers could be under some stress when
this is running.

i had a feeling what i wanted to do isn't possible, but i figured i'd
ask some experts before i give up.
