And remember -- the FreeBSD VM kernel enhancements are already in our
2.0 working sources.  Also, some review is being done to make sure that
the enhancements are either optional or machine independent.  Most likely,
the FreeBSD V2.0 release will have fully coherent buffer cache/VM also.
(BTW -- the working copy of the code is now at least as fast as the
OLD methodology buffer cache code!!!)  The only thing that I know that
we are going to leave out from FreeBSD 1.1.5 is the clustering code -- the
vfs layer clustering with the FreeBSD VM clustering do well enough.  In
fact, the FreeBSD VM clustering is being greatly enhanced...  So, yes when
it comes to porting platforms -- FreeBSD and NetBSD SHOULD be on nearly
level playing grounds -- but the FreeBSD kernel, when it comes out will
be as advanced as ever.
