I just fixed a 15-year-old bug in uxsig.c, noted as item (3.2) there.
Had wondered why `C-c t' never actually worked to write a stack trace
to a file but never investigated why until now!

Also removed the `v' from `vfork' now that Apple has apparently killed
it (untested), so all of these issues should be fixed.

What remains for native aarch64 execution on M1 is to teach the GC to
move compiled code blocks to a separate heap with W^X toggles during
the motion, but that's a bit more work.
