Since rust-lang/rust#121956 we don't need it any more, and we are generally short on Windows staff so reducing the amount of code we have to test and maintain sounds like a good idea. The InitOnce stuff is still used by `thread_local_key::StaticKey`.

@rust-lang/miri any objections to this? |
|
No objection. I don't see any reason to support things like this that aren't used in the standard library anymore. If this is a problem for someone, hopefully they file an issue so we can at least know that such usage exists. |
