Jeff mentions something I've wondered about w.r.t. keepalive (or
"persistent"):  what should the server do on error?  Using his example,
if a server doesn't understand/support GETSHAPE, it returns an error.
Should it also close the connection?  If not, how can the server be
sure it knows the correct position in the (single) input stream at
which to continue?

N.B.  My server closes the connection on an error in the input stream.
