Not Qt clients.  The issue here is with crashes of the compositor itself.
Those are the ones that unavoidably lock up the UI while the kernel crash
handler is being run.

Bug description:
  I can trigger a crash easily on my phone via bug 1262711. Other bugs
  are available.

  When that happens my phone appears to freeze. I am unable to do
  anything for approximately 1 to 1.5 minutes. As a user my initial gut
  reaction is to reboot the phone, thus losing the crash report, and
  wasting my time.

  Having the phone lock up for 1.5 minutes is a terrible user
  experience. Can we fix/mitigate/workaround that?
