When the world was young(er) :> , stack machines, register machines,
and direct memory machines (e.g. TI) battled for domination. Before
reasonable register allocation algorithms were discovered stack
machines were nifty ... but now having a lot (use your own figure of
merit :>) of registers and good allocation is generally
conceeded to be the short path to good performance. 

The recent discussion of adaptive caching reminds me of the remark
(anyone know who originated it ?) "registers are compiler allocatable
caches". 

Bottom line: A stack machine derives less benefit from locality of
             data reference.
