New description:

 !LoopingCall and !TimedService are OK, but it's hard to make sure they
 stop looping before stopService is complete.  This pattern repeats all
 over Buildbot, with some confusing, difficult-to-test code as the result.

 We should have some generic support for this, well-tested, and used
 throughout.

Comment (by dustin):

 See #2480 which suggests adding some randomization to spread out events
 that would otherwise fire at exactly the same time.
