What sort of lock recovery does UNIX / Linux have, generically?

However, folks like Oracle have stuck lock recovery on top.

But, you do need some way to regain control of cores that software has 
run out of control on.

That's either an interrupt, or a way for code running on some other core 
to force the runaway into some known state - possibly killing whatever 
software is running on it.

In 
http://semipublic.comp-arch.net/wiki/Can_asynchronous_interrupts_be_completely_eliminated%3F
I call that "remote control".

There may be some simplifications by only allowing destructive preemption.

On the other hand, when something has runaway and has to be killed, I 
like to be able to see what it was doing.  I.e. I like to be able to 
save its state.  And if you have a way of restoring the saved state...

Ah, now we are getting to the nub.

I agree: I have often found that the best thing to do in an interrupt 
handler is initiate a thread and return - and allow the thread to 
compete using "normal" thread scheduling.

As we have discussed elsewhere, I am not averse to thinking about having 
interrupts (really, I/O events) automatically spawn threads or make 
threads runnable. Or queue up messages for some thread.  And if the 
thread happens to have a core to itself, fine.

Doing so might remove the possibility of the FLIH being messed up.

But, again - this is not a logically complete solution, if there is any 
possibility that such a thread or core can run out of control.

Again, I agree: I have seen several block bits for supposedly 
non-blockable interrupts.

Any architect who says that "this facility will never be interrupted" is 
deluding himself for the short term.

Virtual machines may need to be able to interrupt most OS level 
"interrupt blocked" regions.  Which is okay ... unless there was 
hardware that assumed that could never happen.

This addresses the question somebody else - Stephen Fuld - asked about 
what he acronymized as SSI/HCM (Semi-Synchronous Interrupts/HW 
Cooperative Multitasking).  Why is it easier to be interruptible onbly 
at certain places, not everywhere?  Part of the answer is ease of analysis.

Much of this boils down to atomicity.  Very few machines have had ways 
of making user software define complex atomic regions. Atomicity is 
always relative, so making atomic relative to interrupts would involve 
interrupt blocking, usually an OS level facility.  Atomicity relative to 
other threads and processors is only ever cooperative, using locks.

The great hope of mechanisms such as Transactional Memory, whether HW or 
SW, is that they might give us a way of creating atomicity without 
having the cooperation of all parties involved.

Fair enough.  Many, many, programs do not handle error returns from 
system calls properly, let alone EINTR.

IMHO most programs would be better off dying when such errors are 
thrown. (Not quite Freudian slip there.)

Fair enough.

Although this is consistent with my observation that premature 
optimization is the cause of many, if not most, such problems.
