My user is not in the 'staff' group and its default 1572864 is enough to
start playing a serious game, which eventually crashes when, I presume,
the world gets big enough.

Losing your game/progress like that sucks, so I just doubled the limit
and have been playing without crashes ever since.

Is this fair enough to include in ports or should we aim for a specific
limit?  I see the chromium ports have more logic to a) ensure a limit
and b) present a choice when raising it fails, but none of that was
needed for me so far, hence the simple diff.

Feedback? OK?
