You could think of this as what an OEM might do.

Except it does nothing.

But eat resources.

Yum, yum!

Current we create five processes.  The main process sucks up 16MB of
RAM and creates a full-screen window; only on high-end devices does
the window (and process) use the GPU.

The second through fourth processes just sits there not really doing
anything except using process overhead.

The fifth process runs a background service, slowing eating RAM until
it gets killed by the system (as the system will ultimately do with
background services).  It also creates a full-screen window, and always
uses the GPU even on low-end devices.
