This method could be private on SchedulerThreadPool with a public
PostTaskHelperForTesting() mirror that just forwards to it for testing? Dana
seemed to want it to be on STP as well?

That, or protected with a TestSTP that makes it public with "using".

I don't think that this helper should be in STP. I want to be able to use it to
insert work in a single-threaded PQ in scheduler_worker_thread.cc, which
shouldn't depend on scheduler_thread_pool.h.
