Visual Match is getting itself killed with OOM errors with 11.3.1 os6/Peru
(more or less os32).
Changing card styles causes long delays and increased RAM usage by this
activity. It also likes animating cards moving from one location to
another, which happens poorly on XO-1.75.
The activity can be downloaded from http://activities.sugarlabs.org/en-
