This detailed description of Windows Process/Thread dispatcher (old
and new) seem to have many similarities to OpenVMS. The old was was
written by Dave Cutler.

p.s. Part way through, Arun mentioned that changes to the dispatcher
were necessary to support scaling windows onto a larger number of
CPUs. The last time I heard someone give a similar (scaling) speech,
it was Gaitan D'Antoni describing changes in OpenVMS-7.3-2 which,
IIRC, was related to erroneous serialization on IOLOCK8. Likewise,
both OSs have enjoyed improvements as engineers have analyzed problems
getting their OSs running in a virtualized environment.
