Oh, absolutely.

But that's besides the point.  The point is that software _can_
exceed that limit, even if it's a bad idea to do so; it may not
even be immediately obvious to the programmer, who is most
likely working in a high-level langauge, not assembler.

How will your design accommodate that eventuality?

So ... what, you just don't execute it?  Always skip over it?
Software needs to ensure serial access to some resource.  That's
what critical sections are for.  Your architecture needs to
support that.

From what I gather, you've said to just eschew the atomic event
stuff and build a traditional lock using those primitives.  But
you have also said that a traditional lock can be silently
unlocked if the thread holding it (which, apparently, is an
abstraction known to hardware) is preempted.  It will be like
the lock had never been acquired.

But here's the impedence mismatch: it appears that that happens
_after_ software has already made a decision based on something
that is rolled back later.  If that's mistaken, then say so, but
if not, then the scheme is fatally flawed: there is literally no
way you can use it reliably to build anything that doesn't fit
into your atomic window.

Indeed; that's what I've been saying.

But you also seem to imply that if a higher priority interrupt
comes along and preempts the code that's in the critical section
it will silently unlock the lock that is used to serialize entry
into the critical section.  Is that correct?  If so, do you see
how that makes the whole facility useless for building robust
mutual exclusion primitives?  A lock that is silently released
because something else comes along and wants a turn instead is
no lock at all.

Yes.  Was that the same response where you said the lock would
be silently released if a higher-priority interrupt came along?

Ok, now we're back to the question then: what purpose does it
serve?  It doesn't seem like it can be usefully applied to
anything other than building traditional mutexes based on spin
locks, and even then I'm not sure if that's correct (see above).
