Indeed. These crashes are rare in typical usage, which doesn't mean we
should delay fixing them until Emacs is "unstable enough". It already
is, IMHO, because we take that approach too frequently.

Removing the SIGPROF protection code should allow Ihor's recipe to crash
again. And, anyway, there's no reason for the "supposedly": we know MPS
can't possibly deal with the situation because we've seen the code, so
we should fix it rather than ignoring it because it's rare in typical
usage.
If there's any evidence this cannot happen, I haven't seen it.
GC code in general contains many rarely-exercised code paths. This is
no exception.
