occasional segfaults

[Isaac Dupree]

arbtt-capture segfaults occasionally for me[1].  Valgrind didn't tell me 
why (I think valgrind is better for C and C++ memory errors than Haskell).

So now I run arbtt-capture with this script to restart it:

   while true; do ./arbtt-capture; echo; echo "Whoops dead" >&2; date; 
sleep 30; echo "; restarting" >&2; done

(which works fine, though it'd be nice to know why arbtt-capture 
segfaults :-) )

[1] I think is unrelated to my xmonad-related changes, since it occurs 
at similar frequency with or without them: a few times a day.
