This same issue also applies to the hardware cooperative multitasking 
with a non-recoverable user error if blocked too long I mentioned later 
- the only scheme I can imagine working, as you propose. (Which is not 
to say you may not have other schemes in mind.)

Although admittedly the latter is safer, because the non-recoverable 
cooperative MT timeout is unambiguously an error.  Although losing an 
interrupt is also a detectable error.

This same issue also applies to any shared memory.

If you are saying that message passing is the only RAS-safe programming 
technique, and that shared memory cannot be made reliable

(1) I might be tempted to agree with you

(2) But the world doesn't seem to.  Shared memory is widely used.

Years ago, "concurrent programming" was the hard problem. "Concurrent" 
basically mean "can be interrupted and swapped at almost any point". 
I.e. it seems to me that Dijkstra's interest in semaphores, etc. was 
prompted by asynchronous interrupts.  Nowadays, the problem is 
exacerbated by MP and MT parallelism.

The problems I see are mainly the verdict of history: it's been tried. 
It has failed in the marketplace.

I don't know if it failed because of the hardware cooperative 
multithreading.  Or for some other reason.  But it has failed in all 
instances so far.  I make such historical observations, and try to 
deduce or infer some unifying principles.

Hardware cooperative multithreading with preemption on branches was most 
prominent in the Transputer.  R.I.P. I.R.M.C. (I rest my case.)

I do not know of shipping products with HW cooperative multithreading 
via inserted "interrupt me here" places.  (Although we considered such 
at Gould, and also for Itanium.)

SW cooperative multitasking has commonly been used, e.g. early Apple 
OSes, but has nearly everywhere been supplanted by true preemptive 
multitasking. SW cooperative multitasking was widely blamed for 
responsiveness problems.  (By the way, if you have ever been annoyed by 
a spreadsheet that starts a big recalc, and then is slow to respond to 
^C - well, that is SW cooperative multitasking.)

---


By the way, it may be worth distinguishing user code from kernel code.

User code on most modern systems cannot block interrupts.  Its 
non-interruptible actions are restricted to what is provided by hardware 
or the OS.  (Leading to what I called the "waiting on a non-running 
process" problem, to which FUTEX is a klugey solution.)

Therefore, user code on most modern systems can be preempted at 
arbitrary places.  I think it is interesting that user code is what can 
be cleanly killed on a cooperative multitasking system.

OS code can block interrupts.  OS code is supposedly written by comptent 
programmers.  I might be willing to require OS code to be cooperatively 
multitasked.  (Heck, I know near examples: at Gould we did not use 
interrupt levels for spl, we just blocked all interrupts in most spl'ed 
code.)

However, with the advent of virtual machines, all OS code is somebody's 
user code.
