Thank you very much for your work!

I have one feature request that is related to unwind-protect, filed as
issue #23963:

   https://debbugs.gnu.org/cgi/bugreport.cgi?bug=23963

This is only tangentially related to your immediate patch. However, as
you are now working in this area, I would like to use the opportunity to
ask you for your opinion on this construct. In my view, it would help to
reliably solve a long-standing issue with unwind-protect and possible
resource leaks. Would new instructions help with this construct?

Thank you and all the best!
Markus
