I can't speak for user-space utilities, but using xen as a development 
environment would dramatically shorten the panic and reboot cycle. In addition, 
you don't require a 2nd machine to debug with GDB. Just a thought. If booting 
Linux makes you itch, NetBSD support for acting as the control plane is supposed 
to be stable.
