#1049: Holding the rotate button
 Reporter:  pengo   |       Owner:  dcbw            
     Type:  defect  |      Status:  new             
 Priority:  normal  |   Milestone:  BTest-2         
Component:  sugar   |    Keywords:  rotate, rotation
 Holding down the rotate button can take a long time to recover from
 (presumably due to a large buffer of "rotate events" being generated), and
 when done in the PDF reader (looking at the biomes pdf) it may cause Sugar
 (or something) to crash, and you find yourself at a command prompt. I
 can't reproduce the crash, but I can cause the machine to effectively
 lock-up for 2 or 3 minutes by holding the "rotate button" for a few
 seconds, as it rotates the screen many many times.

 Work around: Don't hold down the rotate button.

 Better solution: Buffered rotation events should be collapsed, so, for
 example, two events received should cause a 180 degrees rotate without the
 intermediate 90 degree rotation. "Shift-Rotate" should go clockwise rather
 than the usual CCW.

 Background: Running a B2 with 303 (upgrade worked fine). Was trying to see
 if there was a way to rotate the screen clockwise rather than CCW ("if
 pressing the button once goes one way", I thought, "maybe holding it for a
 moment will cause it to go the other way.... [crash].. maybe not."

 Other notes: Would be good to have a crash screen that's more informative
 than "localhost login: ".
