[Bug 673389] Re: Clicking on huge image locks/hangs machine (complete loss of interactivity)

[Paul Sladen]

** Description changed:

- Binary package hint: firefox
- 
  Note that whilst I've initially filed this against Firefox, it is a
  wider cross-stack performance issue (a single application should not be
  able to bring the machine down).  Clicking on the following image:
  
  http://upload.wikimedia.org/wikipedia/commons/9/96/Georgetown_PowerPlant_interior_pano.jpg
  (27,000✕17,000)
  
  sets the Firefox title, but then immediately locks the machine with all
  loss of interactivity.
  
  Ideally Firefox should not undertake activities that are likely to bring
  the machine down (such as allocated huge arrays for data that it has not
  yet even received) and ideally the rest of the stack down to the kernel
  should not let a single application bring the rest down.
  
  (Metadata and a tiled-image viewer for the image can be found at:
