No, that's some code that's trying to measure the number of files we are
allowed to open. It expects to fail, it just thought the particular
errno it got was odd enough to report. Might be worth an #ifdef to tell
it that that errno is expected on Cygwin?

As far as the test failure, maybe we are just not allowing enough time
for the stats collector to run? The thing sits there for 2 sec, which
theoretically is plenty, but it's a busy-wait loop and if the Cygwin
scheduler is not aggressive about taking away timeslices then maybe
the stats processes don't get to run. Try doing the test script by
hand, with just a manual delay instead of the sleep function, and see
if it passes.
