So for what exact program(s) are you working? Your solution seems purely
focused on the hard case of a multi-threaded application that's larger
than a single node.

While I'm sure such applications exist, how realistic is it that they're
the majority?

Yeah, the thing that's wrong is you dumping a ~2300 line patch of dense
code over the wall without any high-level explanation.

I just about got to the policy parts but its not like its easy reading.

Also, you giving clues but not really saying what you mean attitude
combined with your tendency to write books instead of emails isn't
really conductive to me wanting to ask for any explanation either.
