Originally, Mach wasn't a microkernel; it represented a model for a
different shaping of threading and IPC on Unix.  OSF/1 which was later
called Digital UNIX was based on Mach, but _wasn't_ a microkernel
system.

And yeah, there's an opinionated/knowledgeable senior Mach person at
Apple.  Tevanian worked on Mach back in the beginning, and is now Chief
Software Technology Officer at Apple...

In view of having someone eminent that has long term wisdom about Mach
and its usage, Apple could certainly do worse than pick that as one of
the technologies.
