I really, Really, don't like the multitasking. I wish I could ID apps to be shut down when I switch away.

I've been seeing video playback stalling, be it youtube or locally stored video. This happens when too many apps are sitting in the background.

The problem mimics stalled streaming. Or rather stalling from bandwidth starvation, which in this case I'm presuming it's the bandwidth of the CPU it's self that is being used up.
