#2443: Generic way to collapse multiple calls to a function, with support for
stopping

Priority:  major        |  Milestone:  0.8.+
 Version:  0.8.7p1      |   Keywords:  sprint
------------------------+--------------------
 In a few places, we want to perform some kind of check at least once after
 every call to a particular function.  A good example is maybeStartBuilds
 -- the master should check for the possibility of starting new builds at
 least once after each call to this function, but not necessarily on
 *every* call to the function.

 It's even harder to make sure that any ongoing check is complete before a
 service stops.

 This is complex to implement, and should be implemented as a utility and
 heavily tested on its own.
