[foreign-memaccess] on confinement (again)

[Maurizio Cimadamore]

Hi,
as promised, here's a writeup on how to support concurrency in the 
memory access API. In the document, I discuss several usage pattern, 
show how they could be implemented (and what are the pitfalls in doing 
so). Then I go on and show a possible approach to get to all the use 
cases with a reasonable API.

The writeup is here:

A prototype for this approach is here:

I'd like to thank John, Brian and Vlad for the many useful insights that 
led to this document.

Cheers
Maurizio
