[boost] singleton and active objects

It occurred to me recently that having the option to make a singleton an active object may be vital in order to make an efficient multi-threaded singleton viable. By having function calls on the singleton enqueue requests and return future variables, threads should be able to access the singleton reasonably often without creating a bottleneck. The question is, should I try to develop and submit an active object library before trying to get singleton accepted? I suspect that having an efficient multi-threaded solution available would help the next singleton review substantially. -Jason
