That's very important, I don't see why it is different between Linux and
Windows here.
Yep, perhaps for timers it was the case a while ago, but with
iothread+dynticks it should not be a problem anymore. For unchaining,
Linux and Windows should have never been different.
Also, why running all the threads on the same CPU would
make the code thread-safe?
It would ensure that two mutators wouldn't run concurrently. In some
sense, signal-safe code could then be considered thread-safe too.
