It should not matter at all, because x_create_frame cannot make the new
frame known to lisp before it is added to Vframe_alist.

This is just doctoring the symptoms.  There is an invariant that *every*
live frame is on Vframe_alist.  If that invariant is violated then this
is the bug that must be fixed.
