More to the point, *any* processor with register windows is not going to do
too well on deeply recursive code.

There are tricks a programmer can do to get rid of some recursion, and some
that the compiler can do, of course.

Some people at Berkeley did some studies with their RISC chip and LISP;
since LISP is generally very recursive, and the Berkeley people seem to like
register windows, those are probably worth reading.
