Some fine-grained control might be nice here. Eg. I could do a major GC as a player is opening a menu, on a loading screen, when the game is paused, or some other key points, and it might still be annoying, but at least it wouldn't interfere with gameplay. There is of course the question of what happens if one of these key points doesn't happen when we need to do an allocation, but... oh well. Perhaps that could be mitigated by saying "I would rather you allocate than major GC right now". Are any of these options impossible, or be unreasonably difficult to implement (I don't suspect so)?
