Well, the fact that it works/fails 50% of the time points to a race
condition. You don't say how the test suites / tests are running, but if
anything's running in parallel, one test's cleanup could be pulling the
file out from under another test's writing results. Without knowing more
about your test runner, this is really guess-work.

Logging to Excel isn't part of the builtin logging module so you've
presumably added that functionality yourself. But PyExcelerator is
ultimately just opening a file and writing to it so for this purpose it
appears to be equivalent to, say, logging a bunch of stuff into a list
and then writing that into a file.
