	   The BSD 4.3 book is wrong then. I just looked at the 4.3 sources
	and it also includes short term waits in the load.

David is correct, the load average is computed from length of
the run queue plus number of short term sleepers. The number is
calculated once per second, and kept in 1, 5, and 15 minute averages.
