if you want an example of double buffered graphics in p9 you can look
at the XaoS source (http://www.acl.lanl.gov/plan9/xaos the relevant
file is in ./src/ui/ui-drv/plan9/).

it uses a single Image and two pixel arrays.  it works on the current
array and when it's ready executes a loadimage() and a draw()

pretty similar to Russ' solution
