This is especially true for a hard-switch wrapped in a soft switch, i.e. one where a "jump_soft_to_hard has been put on the frame.  Until that jump is actually performed, one cannot switch away from that tasklet.

My worry about the potential fixes you have described for this bug,
are that they are top heavy for what they are addressing.  Let's be
honest here, what we have is a case that crashes that no-one would
ever do in production.  Making larger fixes than the problem itself,
well, I wonder if we are incurring additional codebase complexity for
little benefit.

I say let this one sit.

Cheers,
Richard.
