Do you have links for this?

According to this, each app runs as a separate user and a separate
Linux process, on Android:

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!") :-)
