Chao Shi commented on CRUNCH-318:
---------------------------------
I used to hit this problem sometimes.
I see this patch adds a sleep after "copyResourceFileName" to tmpdir. I think
we are doing all such things in other tests, but I cannot figure out why the
others do not fail randomly. What is the difference between CheckpointIT and
the others?

> This appears to be due to a timing issue. I can't find any problem in the
> code, which appears to be taking the correct path and checking the modified
> time of the underlying checkpoint.
