This is correct.  OSF/1 is a significantly enhanced Mach 2.5 kernel.
2.5 was built into the side of 4.3 BSD, and while it is threaded
internally, it is still a monolithic system that provides both Mach
and Unix system services inside the kernel.  Work is proceeding
on OSF/2, but there's no announced release date and member design
meetings are still being held.
