That's not true. .dlls are the primary use case for this. If a .dll
has it's own local memory and local allocator, this is a big,

what's the advantage of this over the stanford style?

You don't want to use an amd29k (even if you could get one).
They look cute on paper but their freeze-mode interrupt
handling is a Chinese puzzle and unless you use Ken's compiler
(previously called 9c), you're stuck with register windows,
which tend to need to be spilled when an interrupt occurs,

if you mean thunder, that machine is getting turned off soon. What new
machines have made it on top500? Sorry I
I know most everyone here hates the Itanium, but it is in some pretty large and
fast systems, and it's on the Top500 list.
So out of curiosity, has anyone looked at putting together a compiler for
Itanium, or otherwise looked at a Plan 9 port?
