The Solaris model derives from work done in 1993/1994, jointly, by USL and Sun Micrososystems, on the SVR4.2 release code. That's why the UnixWare and Solaris models are so similar, up until the last few years, when the Solaris model changed. FWIW, I think the Solaris model changed in order to better support NUMA, without needing extensive scheduler changes, not because it really has no bugs now. 8-). -- Terry
