I seem to recall that Win9x opens only a single socket connection to a
server and performs all operations for all shares and security
contexts across that socket. smbclient is a more "normal" unix
program in that each instance of the program opens its own socket.
I'm not sure what to do about this -- it might require a big change
inside Samba -- but hopefully it's a useful start...
