I have ported a suntools application to X that times how long it takes
to render an complex object.  I have an X11R3 that draws approximately
20,000 vectors. (the object is a complex diagram)
Using separate calls to XDrawLine() (I know I should use XDrawLines()
but I have my reasons)

I would like to know if there is a way I can block program execution 
until the X server in question has finished DRAWING all that was
requested of it.
