Well, DragonFly is definitely not a microkernel. We forked off of
FreeBSD, after all, and that is a fairly monolithic kernel. I like
the microkernel concept but putting core elements of an operating
system into their own protection boxes result in fairly significant
performance issues.
I think L4 and Mungi have proven that doesn't have to be the case these days.
