The keyword has different meaning
depending on the language and
context.

Most of the time to prevent optimizations by the compiler to insure write 
ordering
and some consistent view (Java use).

Not here. It's meant to warn that
nothing is guaranteed, no synchronization, no consistent view.

It should be kept local (no leak
outside of a narrow scope) and 
certainly not shared
by multiple threads.
