I found myself running
vsockclient 2 1024 true
in a situation where it just mattered that a connection was made, and
no data needed to be exchanged of it.  That I found myself doing this
is quite a strong indicator that the program to exec into should be
optional.
UCSPI-1996[1] doesn't specify what should happen if no application is
provided, so I think this is a reasonable interpretation.  I'm not
sure if I feel the same for vsockserver(d), so I haven't made the
corresponding change there.  I'll wait to see if there's ever a need
for it.
