The De-activate/re-activate plugins routine nightmare

[superbask]

I'm still on PT8 so maybe they've fixed this in 9, but if not, PLEASE give us a choice to continue or not if there is insufficient DSP to instanciate another plugin ( or track, send, whatever).
If the session is running, it says " PT must be stopped to do this" so it obviously knows that it's going to go into the re-allocation routine. I waste hours and hours on this, you can't cancel it, and sometimes PT just hangs anyway after a while.
