Sorry for the delay. Things have been backing up... We tested with tis series and found there was no performance change in our test suites. (We don't have a good way to share the actual numbers outside right now, but since they aren't really different it probably doesn't matter much here.) The difference we did see was a slight decrease in the number of tasks moved around at higher loads. That seems to be a good thing even though it didn't directly show time-based performance benefits (and was pretty minor). So if this helps other use cases we've got no problems with it. Thanks, Phil --
