  29  * The Task and Service tests need to do a little trickery due to threading.
  30  * Although in practice they run on different threads (ie: the UI and
  31  * background threads), while testing I want to be able to run predictably
  32  * and quickly on just the test thread. This implementation of
  33  * Service is used as the base implementation of all Services which are
  34  * tested. It will simply run the given command immediately, and makes
  35  * sure the checkThread does nothing.
