Go ahead..
Btw, I wouldn't worry too much about the false sharing on a 128-byte
cache-line. Let's face it, we're unlikely to see many P4+ class machines
with less than 128MB of memory, at which time it starts to get unlikely
that we'll see all that many horrible ping-pong schenarios between CPU's -
touching alternate physical pages simply isn't all that likely.
