I increased the tolerance such that that occurrence wouldn't fail anymore:

Is this a different failure of the same test?

Comment 3

[David Baron :dbaron:]

That's the timing failure; there are some comments late in bug 435441 (e.g., bug 435441 comment 104 and bug 435441 comment 107).  Probably better to track it in this bug.

But I do want to test something about real time and not just give up on hoping we can test something related to it on the unit test slaves.  The error above shows it missed the 750ms error window by being nearly 1s off.

I made it so that we only report a TODO rather than an UNEXPECTED-FAIL when the wall-clock timing is off:
