Change 96113 by jb@jb_freebsd2 on 2006/04/25 22:21:03

	Woo-hoo we've got a trace enabled at last. Just a simple 'dtrace -n BEGIN',
	but that's the DTrace equivalent of getting a 'hello world' program to
	compile for the first time. Remember doing that? I can. Just.
	
	Now we're up to the sleep loop waiting for some feedback from the dtrace
	device. That means it's time for the nitty-gritties (TM).
