Description

It is possible that an index file could somehow be left on the filesystem with no corresponding log file. This is not currently handled well. If the .index file happens to fall on the same offset as a new log segment, then when that segment is created terrible things will happen.

We should check this condition on initialization and add some unit tests against it.
