Mm. I don't think I believe that. For example, of your makefile had at
the top:
.PHONY: all rx ry
all: rx ry
rx: ; $(MAKE) x
ry: ; $(MAKE) y
then I think "make -j all" gives you the same behavior.

I doubt that as well. I've already described this in my last message:
these two constructs are identical in function _UNLESS_ their prerequite
subgraphs overlap somewhere. If they overlap, then the result is not
deterministic in general: it may work fine, or it may fail miserably.
