I think I have an answer for you and Lee is right.

I wrote a simple looping program that would show the elapsed time for nnnn 
passes through the loop.   Run by itself, a valid time would be 1.55 secs for 
one pass.   Start up another copy of the same program, and the time for each 
became   2.9.   Close enough to twice the time that it's obvious the HT is a 
sham.
