Initial tests with template that only syncs and one that prints "hello world".
sync-only - first run went to 16,936k in about 12k/sec increments then down to 16,904 stablish;second run 17,360k, stopped, dropped to 17,304k and stablish
with-print - first went up about 12k/sec to 17,760k, dropped to 17,048k and stablish; second went 16,760k (started at about 15,480) and stablish
I left both running and now the one that does nothing has crept up a bit to 17,564k and the print only is about 16,900k and both are fairly steady.
I think the AppGameKit engine actually gets upset if you don't give it something to display.
I added a sprite made with image zero (white), (second run) started at about 13,632k and went to stablish at 14,640-14,644k.
Next, a sprite from an image. start at 16,180k went to stablish at 17,328-17,380.
It looks like it takes a bit to decide where it is and then gets sort of stable, as long as nothing changes.
