    I tried really hard to make an integration test showed the initial error reported in ACCUMULO-4157,
but it was too hard to control the moving parts make a WAL be deleted before it should have
been.  My work is [here](
if you want to look.  It is ugly and didn't work, but maybe will give you starting point.
 Or maybe it is just an example of what not to do.
