----------------------------------------------------------
I don't think this is related to GEODE-7015.
It's probably just some basic multi-threaded flakiness in the test itself. It
has a looping background thread with a 10 ms sleep. Fixing this ticket probably
requires tightening that up in some way.

> This test depends on a background thread waking up every 10 ms to perform a
> GET which prevents another thread from expiring an entry. I think that would
> be very prone to failing if the thread loses CPU for any reason.
