Dear Bill and whole RMA working Group,
I tried to bring all my knowledge together to solve the
"shared memory synchronization problem".
I know, that you Bill also wanted to solve this problem.
Please take my ticket
as a basis or stone quarry or ... .
For me, it is important to really find all locations that must
be touched to solve the Problem and to have a consistent solution.
I hope that I found all of them and my solution is consistent.
The solution is free of technical implementation internals,
i.e., the local memory barriers are only mentioned in a rationale.
I hope you all enjoy the proposal and it is a basis for
