JavaMemoryModel: Stuff on Pentium memory barriers

There was a lot of stuff in the linux kernel digest
a while about about data races in the linux kernal,
the memory model for pentiums, and what instructions
are needed on the pentium to force a memory barrier.

Search Pentium "lock prefix" "memory barrier" at google.

I still don't feel that I have a definitive understanding
of the issues for pentiums; the people on the linux
mailing list didn't seem to come up with a definitive
answer. I'm just amazed that Intel can get away without
providing clear instructions on how to do a memory barrier.
