Go in Window on Mobile / Not Obeying Purge?

[J. Landman Gay]

On Android, if you leave the app, the OS will remove it from RAM if it 
needs the memory. It sounds like iOS is doing the same thing. Since 
SivaSiva is so big, memory may be tight enough to drop the puzzle stack 
when you come back to the app. It would depend on the RAM in the device.

I don't know of any resume messages, though I wish we had them.
