Okay, thanks Zachary.   A while back we had some flapping tests that would
oscillate between unexpected success and failure on Linux.  Some of those
might still be in that state but maybe (!) are fixed.

Anyone on the Linux end who happens to know if the fails in particular look
normal, that'd be good to know.

Thanks!
