	Hmmm....kernels track usage of a filesystem by the number of
	open files in a filesystem. If a file is open and has been
	deleted, its contents will not be freed until the last close.

u> verifying the password
u> 
u> 	- telnet into the server taking interminable periods of time
	"telnet" attempts to figure out what the name of the client
	machine is. This might take a long time if its winds down to
	DNS.
