With timing types of bugs it often helps to mention the hardware you are
running on, especially if the test has any sort of threading. Often
number of processors/speed of processors is the cause - and often as you
have labeled it, it is a test problem (rather than a code issue) not
expecting the type of timing one gets in such an environment.
Historically the tests have been run mostly on single and dual processor
SLOW machines.
