Hi Coleen,
From the comments of the bug, it looks like we are still not sure
whether this happened because we're just running on a slow machine, or
whether there's is an real underlying issue.
Since the test fails very rarely (a few times a year??), if we are
modifying it, maybe print out time stamps after every iteration? So if
this fails again in six months we will have more info to look at. E.g.,
if the time stamps are well spaced out, we know we're running on a slow
machine. If the time stamps get progressively longer, we probably have a
bug in the test or in the VM.
Thanks
- Ioi
