Comment(by viboes):

 The difference is that as far as you have a timeout you will be wake up
 and the the interruption check point will be done. You can pool with a
 timed_wait with the granularity you want to achieve the behavior you want.
 Other than polling I don't see any other solution. And make the wait
 function pool on a default granularity will penalize the users that don't
 need to interrupt the thread.

 It is also true that the documentation let think that wait will be
 interrupted if a interrupts is signaled, but it does this only before and
 after the underlying wait.

 "The following functions are interruption points, which will throw
 boost::thread_interrupted  if interruption '''(BEFORE CALLING)''' is
 enabled for the current thread, and interruption is requested for the
 current thread: "

 Maybe the library could add a interruptible wait with a specific
 granularity.
