Re: JavaOne - papers on HotSpot
> Thread Synchronisation: Performance Breakthrough
The HotSpot JVM is good news. JavaPP/occam will simply ride on the back
of it. JavaPP offers security through a simpler and theoretically sound
programming/design model, imposing `practically' no additional overhead
on that imposed by the underlying JVM.
Sun don't actually quote any times yet for the HotSpot `breakthrough'
synchronization mechanism. KRoC now sports a 122 nanosecond context
switch on an UltraSPARC, still using the transputer algorithms designed
and implemented 15 years ago ...

I think they've been reading someone's occam course notes!
