Fix bug 3789: Turn off assert in automated tests for timer latency. This test isn't helping a lot, so removing it has no  negative effect.  But the test fails on some VMs which run horribly slow.
Fix bug 3789:
Turn off assert in automated tests for timer latency.
This test isn't helping a lot, so removing it has no 
negative effect.  But the test fails on some VMs which
run horribly slow.

Leaving the test in place because it still prints out
timer perf information, which can be useful for testing
on laptops, low-end machines, etc.
