Thanks. For comparison, on my Linux/Athlon 2600+ I get about

<java> FillRect2 

 14 msec/4097 fillRect (jamvm+classpath and your limit_gdk_flush_rate patch) 
  4 msec/4097 fillRect (JDK 1.4.2)
  1 msec/4097 fillRect (JDK 1.6.0)

and with <java> FillRect2 -size 200    (more won't fit on my screen...)

195 msec/40001 fillRect (jamvm+classpath+"gdk_flush" patch)
 41 msec/40001 fillRect (JDK 1.4.2)
 13 msec/40001 fillRect (JDK 1.6.0)
