Do you have links for this?
According to this, each app runs as a separate user and a separate
Linux process, on Android:
http://developer.android.com/guide/topics/fundamentals.html
GUI based apps are suspended when they are in the background, but that's
not due to Linux, that's due to Android's design.

I'm not sure it's an advantage, given iPhone 4 and Android are already
preemptive multitaskers, with Android being more "wild west" in its
background processing philosophy. (i.e. "You want a background service?
You got a background service!") :-)
