That's why exokernel was mentioned. Although a microkernel, Mach provides
mechanisms and structures for higher-level abstractions. There's a
distinction between having a library server which emulates to the
underlying OS and actually having separate task structures for different
processes. This is also why, although the predecessor and instigator of
exokernel, SPIN is a less close fit.
