when sd card is umounted, android sends a message to apps. I can't

figure out how to get that so I ignore it and am killed then
relaunched if I have a dict file open on the SD.  On relauch, don't
crash.  Instead, check if any dicts used by the game is unreachable
and put up an alert with only one choice: Close game.  Thought about
using the missing-dicts stuff from GamesList, but this is a special
case that should be seen only when user umounts while a BoardActivity
instance is frontmost.
