Thank you for your patience and willingness to explain. I was completely
missing that there are two different issues, my bad, and only *one* can
be dealt with via compare_and_swap, the other needs anyway plain locks.
All in all, given the very delicate points at issue I don't feel like
bringing in, so close to the release of 4.0.0, the compare_and_swap code
and the additional complexity and configury problems (+ testing that
everything behaves as expected on all the targets!!). Do you, Gaby?
Please, let's try to provide a decent implementation, let's ask Jonathan
to prepare (1) for 4.0.0, then we can discuss further improvements in a
second moment, when this code will settle a bit.
Paolo.
