flushing stuff out to monitor

Dunno if you have tried this, but R_flush() is designed to do just that.
There is also a R_stabilize() which I have used but don't remember off
hand exactly what it does.

In v.digit I have:

V_flush ()
    R_flush ();
    R_stabilize ();     /* needed for X windows */

And call it whenever I am done drawing something and am waiting for the
user to do something.
