A little bit. rr was written with cross-platform support in mind, but
the more we work on it the more linux-specific it becomes. At this point,
I'm pretty sure it'd be easier to write a new tool from scratch than port
rr to windows.

Not to my knowledge. Porting rr to windows is approximately as complex
as porting valgrind to windows. But as the valgrind people say, "In
particular Windows is not under consideration here because porting to it
would require so many changes it would almost be a separate project."
However, also as the valgrind docs say, "(Valgrind + Wine can be made to
work with some effort.)". We have  on file for that.

I'm don't know, but I'm pretty it does. If it didn't, they could be
exposed through a driver.
