There are race conditions in your code. In between the time you execute
"curTime = time.clock()" and calculate "curTime - self.timeStamp" in one
thread, the other thread can execute "self.timeStamp = time.clock()".
It's the only way your example program can print a negative "Actual
Elapsed Time" value. The race condition seems unlikely, and it's hard
to explain how this could result in it printing a value in the range
of -3.5 to -4.5. However, a race condition occuring between the two
evaluations of "curTime - self.timeStamp" is the only way your example
program could print a negative value.
