I thought it was the only way for me to get you to even consider the
possibility that your ideas of how GC works with MPS may need to be
corrected.  Given your message, I currently think there is no way for me
to do so at all.

I give up.  (Certainly on this discussion, maybe on scratch/igc, who
knows.)

The MPS-based GC in scratch/igc does not allow or require general Emacs
C code to make "no GC here" assumptions.
