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](https://github.com/mjwall/accumulo/blob/62b0e879cbc00773d1fbdbada9d696d42ecd6531/test/src/test/java/org/apache/accumulo/test/functional/GarbageCollectWriteAheadLogsIT.java)
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.
