Whoops, I messed up the rebase at first.

You need to run ./miri bless, too, in order to update the .stderr files. You may have to run this for multiple targets to make sure they're all in sync in their behaviour

I've rewritten the handle implementation based on what is actually guaranteed by the windows docs

Thanks for the PR! Looks like Windows is starting to catch up with our Linux support. :)

I am working on a review, but in the future it'd be helpful to break PRs into smaller chunks. For example, I think this could have started with just thread spawning and joining, without all the concurrency primitives. Smaller PRs are a lot easier to review so any effort you can put into splitting a change into chunks is much appreciated.

This looks great overall, very nice!

I hope all the new code you added is actually covered by tests. For thread spawning and the synchronization primitives, I would think the existing sync tests are enough, though I do not know if the stdlib actually uses these primitives.

I did not see a test that would join on a thread with a timeout, so that will have to be added (or the code for that be removed again). Also there are no new failing tests, which is a bit of a concern given that the pthreads primitives have a lot of failing tests to ensure that misuse of the pthread APIs is detected.

Looking at your commits, I see "basic threading" and "condvar, parking and yielding" are separate commits. If you could split those into separate PRs, that would help a lot with reviewing.

Basically the first PR just needs to get concurrency/{simple,thread_local,tls*}.rs to work. That should be possible without new synchronization code I hope?
