This sounds a bit like what was once known as Burroughs Large Systems
(then Unisys A-Series and now Clearpath or something) architecture. It
had processes, not threads, but processes can be related and can share
data.  Every process has a stack, one stack can have a reference into
another stack, and unfortunately, that's about all I can remember at
the moment.

There are architecture reference manuals out there.  The data
reference I'm thinking of is called a Stuffed Indirect Reference Word,
which might give you some idea of what you're getting into.
