Of course, sorry. Seems I missed most of them.

About Pause in all VM ops, an alternative would be to just check in the trimmer if we are at safepoint, and if yes treat it as pause. I'll see if that's easier (I'm worried about pulling a mutex or atomic increasing the pauser variable in every VM op we run).
