John has been talking about doing this for a while -- clustering the kernel threads into a smaller number of kernel processes or a single kernel process. This is the approach Darwin takes as well, FWIW -- they have a kernel_task in which all the various kernel threads hang out, which avoids the overhead of full processes, as well as the emotional baggage. I think I saw John put it on his TODO list in Perforce, so maybe it's coming soon :-).
