Has FreeBSD considered this?

Last I knew, no.  I was under the impression, the work FreeBSD did rewriting the Mach stuff paid off for them at the time.  I have FreeBSD, OpenBSD and Linux (and Mac OSx) all running on my systems here.   But the problem is that the HW is all over the map in termns of release date, so I'm not sure which is faster at this point.   The *BSD systems are the easiest to admin and clean/simplest (which is why they only systems I have exposed is an OpenBSD box).
