The other case that came to mind was signal handlers. What happens
if we're using the global register as a scratch, we hit a memory
reference that faults and inside the signal handler the original
code expects to be able to use the global register the user set up?
If that's a valid use scenario, then there's probably all kinds of
DF stuff that we'd need to expose.
I'd say that's a valid assumption. Though maybe we want to be able to
change semantics with a flag here.
A flag seems like overkill, I don't think people are likely to enable
that ever.
So what's the consensus here, closed wontfix?
