However, barring any bugs I discover after writing those tests, I believe the implementation itself is feature-complete with respect to the proposal. Given that it is a nontrivial patch to a somewhat unloved portion of GHC, and given that there are a couple questions I have about how best to go about testing certain interactions in the first place, I figured I would reach out and see if anyone particularly familiar with the guts of the RTS would be willing to volunteer some time to give it a careful look.</div><div><br></div><div>The good news is that the patch is not actually very large, and it changes very little existing code: the diffstats currently sit at +1,078 -48. For those interested in taking a look at the patch, I recommend starting with the Notes mentioned in the MR description. I suspect they may be a bit sparse at the moment, so please do not hesitate to ask questions; I will do my best to respond promptly.</div><div><br></div><div>Many thanks,</div><div>Alexis<br></div></div>
