IIUC what you mean by PIE, it requires a dumped Emacs where the position
of the (pre-filled) heap can change at every invocation.  If so, that
means relocation of all the pointers in the heap, at startup.

I had the impression you didn't want such relocation-at-startup (since
you used it as an argument against XEmacs-style dumping into a separate
heap file).
