That's not useful.  Crashing (or rather being killed by the OS) happens 
all the time on tablets and phones.  You get killed for using too much 
memory, for not being active while other stuff is using too much memory, 
for just not being active, etc.

So in practice this needs to be handled somehow, no matter how much we'd 
like to avoid thinking about it.

On phones?  We should be expecting the former (tab gets killed) pretty 
often.  How often the latter will happen depends on how much we give 
authors in the way of tools to handle it.
