Alan,

If that is true "in depth", there should be no FUTEX-relevant  code,
neither in the Kernel, nor in the library, that should be considered
"arch-independent".

If so, we could happily create a "atomic hardware RAM" - based (or
whatever type of) FUTEX for the arch in question in the arch's source
files, without needing to take care of what happens in the rest of the
Kernel or Library code.

Provided this implementing the idea I presented might be a doable task.
