Review Comment:
I'm a bit confused at this, taking a closer look. The `SingleThread`
implementation seems to not override register, even though it seemingly has no
reason to use the `Unsafe` implementation, since it is able to just consult its
`Thread` register, as this is of course much simpler and cheaper.
However, the `register` method only makes logical sense for the
`SingleThread` implementations? The others need to surely maintain it on
entry/exit?
