Time based is not good enough given the resolution we are talking about here. 
We want to be able to terminate after ~100ms worth of execution, but at that
time scale, we'll get a lot of false positives due to the thread being
interrupted by other processing on the system.  So, we need to count something.
 Maybe counting getTime calls is not the best solution, but we need to count
something other than elapsed wall clock time.
