Isn't that backwards?
I thought cache conguency was a problem when the same physical
memory was mapped to different virtual addresses.
Surely here we are tring to make the same virtaul address reference
different physical memory on each cpu.
Or is the problem in the shared accesses used to setup these pages?

Maybe the setting the cpu to TSO might hide some store-buffer issues?
