All tasks having the same group key will be stored in the same queue, which means that they will be associated with the same lease. The exec_order column defines an execution order for tasks within the same group. Tasks with a lower number are executed first. The commit also adds/updates TaskSchedulerTest to use RxJava's TestScheduler. It took me a good bit of time over the weekend to understand how to set things up, but it was well worth the effort. Tests will be much more reliable, consistent, and faster as they use a virtual clock.
