If someone is crazy enough to do that call inside a finalizer, then
why not let his wish come true?

Actually the `n' argument is not working properly, but in the other
direction, it seems. A call to LUA_GCSTEP does roughly one GC "step", no
matter `n'. (A quick test took some 350 step calls to perform a full GC
cycle.)
