Just out of curiosity, are you [set] up to run LKMM locally at your end?

I don't know what exactly that means. I generally run it on wetware.
But I sometimes ask Hernan to run Dat3M (on his machine) over all the litmus tests in your repo to spot any obvious problems with variations I consider.
I don't think Dat3M is feature-complete with herd at the moment, just unbelievably faster. For example I think it ignores all flags in the cat files.
Oh, I just remembered that I also installed herd7 recently to make sure that any patches I might send in satisfy herd7 syntax requirements (I think you called this diagnostic driven development?), but I haven't used it to really run anything.

Is it too obvious that my words usually aren't backed by cold machine logic?
