Review comment:
i'm actually just trying to use this to debug the regression, I couldn't
reproduce the gpu failure on my side. but, now i've found a node where i should
be able to run tvmai/ci-gpu, so i'm going to take that approach.
for merging, I don't know--I know we had issues with the CRT being flaky in
the regression before. it might be worth it to leave this code in, since flaky
test failures are almost always solved with more data. so, i'd be happy to put
it behind a `#define` and enable that for the regression, if you're also happy
with that?
