When I started working on a PDP-11/70, I was told by someone or other that the
architecture of that machine was such that cache references were actually
FASTER than register references, and therefore ints should NOT be declared
as register ints.  Registers should still be used for pointers which are
being referenced through because that can be done in one instruction if the
pointer is in a register.

Question: what is the right register strategy for the Vax?  Does it vary
between models?
