> As part of a rollback from a rolling upgrade in progress, we discard edit log
> segments by renaming the file with suffix ".trash". If no new edits arrive
> in between multiple attempts, then the ".trash" file may still exist. On
> Windows, {{java.io.File#renameTo}} fails if the destination already exists
> though. This is visible right now as a failure in
> {{TestRollingUpgrade#testRollback}} when running on Windows.
