You have GC in games, but you limit it to a small set of objects 
(<50000?)
So you can have real time with GC with an upper-bound.

Putting everything under GC is probably not a future proof 
concept, since memory capacity most likely will increase faster 
than CPU speed for technical reasons.

Yes, but you don't blame the application if the scheduler isn't 
real time friendly. Linux has been a been kind of bad, because 
distributions have been focused on servers. But you find real 
time friendly schedulers too.
