Re: [PATCH v5 0/2] MR4049: ntdll: Implement thread-ID alerts using kqueue()/kevent()

[Brendan Shanks (＠bshanks)]

Thanks for sending this, I added some comments but overall it looks good.

I think it would be better to put the `ulock` commit into a separate MR, at the very least that will need a version check or `dlopen()`/`dlsym()` to handle pre-10.12 macOS.
