	Not directly: on the application side, wrapping the
	write(2) in calls to a timer will suffice.

	Ah: different question.

	I haven't thought about a "single statistic" for Samba:
	they usually require a better brain than I have (;-))

	Stealing an idea from the Unix definition of "load", we 
	might report the number of SMBDs waiting for disk i/o 
	and the number either wating for CPU or running.  That 
	would be a "figure of merit" that might well match the 
	intuitive definition of	"how hard is samba working"....

	Cool idea...
