Title:
  Clicking on huge image locks/hangs machine (complete loss of
  interactivity)

Status in “firefox” package in Ubuntu:
  Fix Released
Status in “linux” package in Ubuntu:
  Incomplete
Status in “xorg” package in Ubuntu:
  Expired

Bug description:
  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.
