	Unfortunately, NT doesn't realize that it should tell

	Samba can't do much about this, but it can be told to
	clean up the old (now disconected) smbd process. Do try
	"keepalive = 60", and we'll see if the code path
	allows keepalive processing to run while there is a
	read outstanding. 

	If not, we'll probably have to raise this on samba-technical
	and see if there's a way to do so. Hmmm..., or perhaps a 
	way to detect excessive HSM/NFS delay at read-time.
