Just reading some code,

On VAC architectures it may be beneficial, during context switches, to
check the vmspaces of the from/to processes in order to check if they
both exist within the kernel. If this is the case, it is possible to
switch faster because the mappings don't need to be changed. Under,
like, a heavy pagedaemon, this could make a difference.

Now picture an NFS system running a few nfsiod's. Would it be possible
to implement them as kernel processes for the same reason? Just a
thought.

Is this nuts for some reason I'm not considering?

	Regards,

	Neil
