From my reading of the x86 source, one of the things Julian did
was seperate out the allocation of stack pages, using a defined
value.

This may be as simple as putting a larger number in your config
file... I don't know what the Alpha default was before the change,
but I do know that it runs 8K pages, which if KPAGES is in 4K
chunks, might have reduced your stack size on you...

Not brilliant, but something to try...
