Is there a way to globally limit Flash Player frame rate to release CPU resources?

http://superuser.com – On modern PC, with quad cores you sometimes can't just watch simple video normally. The reason is, that for example ad banner in another browser tab can kill flash efficiency (with is single-threaded) and cause that simple video on youtube is jamming. Can we prevent this situation in any way? I mean for example: restrict flash player maximum framerate run flash player on more threads pause flash on invisible browser tabs limit CPU usage for single flash object (HowTos)
