What do games these days usually do when the player spams the quick-save key (presuming that there is one)? Do they queue up saves? Do they ignore quick-save presses while saving? Something else?
(This arises due to my current intention to move part of the saving process into a separate thread. This means that the game should, hopefully, no longer stall when saving the game. However, it also means that the game is still taking input while saving–including input from the quick-save key…)
I suppose, come to think of it, that the problem also applies when saves collide–if, for example, the player runs through an autosave trigger just after quick-saving (or vice-versa).
