Looks good here. Particularly, removing generational collection
(as with disabling it in work4) brings lua5.1's former memory
growth problems quite well under control.
I still find gcpace a bit high for my tastes (I reduce it to
135 for a ~30% drop in peak mem usage and no measured performance
change), but that's a minor matter, and overridable at runtime,
so I'm happy.
One GC observation which might help or interest someone is that
(absolute-speed measurements aside, which within reasonable
tuning ranges didn't affect the performance of my applications)
changing gcpace within the 130-200 range doesn't perceptibly
affect 'smoothness', while changing gcstepmul within the 200-800
range increasingly caused noticable pauses in the game (like lua
5.0's GC pauses) as gcstepmul increased.
Everything seems stable and predictable here.
