  We run a Unisys A-series host and when I ran the heavy test against it
it got REALLY busy, except for the console it was pretty unresponsive.  When
the test completed it came back fine.  It appeared that one of the processes
that handles TCP/IP stuff got very busy during that time and since it runs
at high priority it kinda took over the machine.  This machine is also fairly
"tight" and would have had very few ports open.  Maybe there is a connection.
