fs-storage-test.c++ failure

I'm having trouble reproducing this right now, but earlier today I was repeatedly hitting this test failure:

It seems like this happens roughly 50 percent of the time when I do make continuous. It only ever happens on the first run; if I run the test binary by itself, or if I trivially edit the source file to get it to re-compile and re-run, the test always succeeds.

I do actually run into this! I thought I didn't but I wasn't read the logs. I also am OK ignoring it for now on my system.

My guess is that this will be "fixed" when we switch over to the new storage stack I'm working on. :)
