Are you saying that file-exists-p is the only primitive whose
redefinition could screw generation of trampolines that follows?  I
though redefinition of additional primitives could potentially cause
similar problems.  Basically, any primitives that are called by the
code which is involved in producing a trampoline.  Was I mistaken?
