OK, this is what I was talking about:

You can probably see now that there are different parameters that can be configured for the patch, with different time/space results: when it runs (on allocation failure/on low memory mark/before any allocation (quite extreme)) amd how it runs (step or full). And probably other parameters that I can't find at this late time :)

I see.  The performance implications are pretty extreme as well.

I guess some other tests that I'd like to cook up would be how LUAI_GCPAUSE affects those numbers as well, and also something showing the variability in loop timings depending on which is in use.

If I get some time I'll run some numbers there, since I've been doing a bit of testing around memory growth when running scripts like adcscope.

OT: My next major goal, though, is getting RPC working (should be pretty easy once I finish a bit more refactoring).  I'll talk about it a bit more soon.  I suppose I should also clean it up a little and see what the folks on the Lua list think once it's working with the generic transport layer.
