In testing we have seen the following failure in the cleanup of a failed index build:

I've tested attempting to reproduce and was unable to get the system to fail in this manner again.
Looking at the code, I believe that we could handle this error case slightly better and retry the failed cleanup instead of just issuing an fassert.
