unix vncviewer: strange behaviour

This is certainly odd behaviour, but a server should be made capable of
handling multiple update-requests like that (simply coalescing them into a
single large update, for example).  Most viewers are capable of creating a
"stream" of incremental update-requests, most commonly while scrolling a
small window across a large desktop.
