But that's exactly what Hydra does (thus my question). Hydra uses
separate object memories for (as you phrase it) "on OS-thread per
scheduler". Therefore it allows all the existing code to continue to run
with the current assumptions about threading (i.e., green threads only)
and requires new code to be explicit about the concurrency model it
assumes (i.e., channels for communication between the images).
