>
> the perf eval tool for the wal never sets up a log roller and instead used to
> just call the rollWriter method directly.
> Eventually it changed to call requestLogRoll instead of attempting to do the
> roll itself. requestLogRoll is the same method used internal to the wal code
> and it relies on there being a LogRoller to actually have rolls happen. (the
> method just notifies all of the listeners for hte wal that one of them should
> call the roll method.)
