Heh... no kidding... How often does my X11R6 Xsun crash?  Oh, often,
especially if I'm using later versions of Netscape :-)

I'm told that the reason NT moved graphics from being a "process" (actually,
something very similar to a Mach server) to the "micro"-kernel was for
performance..  However, I don't see _any_ performance problems with
X on my NetBSD systems, with the one exception of NetBSD/hp300's R5 server,
which is slow because of a crappy ddx layer.  Even X under NetBSD/sun3
is reasonable, and XFree86 is nothing shy of _amazing_ on the 200MHz PPro
in my office.
