I agree being able to put a hard limit, in some situations, might be nice. However, I believe the current implementation pretty much leaves memory management up to the OS, which, hey, I'm no expert, but sounds reasonable to me.
MongoDB won't starve other processes of memory unless the OS decides it should. It seems like the best way to leverage the most amount of available memory.
