As I explained in another message, it seems that keeping Lua better
informed of the memory in actual use seems to have a negligible impact
on the collector (except for making it run a little slower). Unless
someone gives a good argument that this undestanding is wrong, I cannot
see why it would be a good addition to 5.2.

In Lua 5.2, on the other hand, the 'x' in collectgarbage( 'step', x )
will correspond exactly to the work the collector does when allocating
1KB of memory, so it should not be that tricky to set it.
