The root issue is that this code is trying to return a unique file system
path that meets two conditions:
- The path does not correspond to an existing file.
- Files / directories created at that path will be cleaned up by the test
suite.
I think this was the intent expressed by the original
`Random.nextString(10)` code. One approach would be to have the _directory_ be
random and per-test and to just use a fixed filename within that directory.
This precludes parallel execution of the tests within a single copy of the
write-ahead log suites, but I don't think we're pursuing that type of
parallelism right now so I don't think that will be a huge deal.
