Ok, task is for Qt clients to intercept the sigsegv signal, and in a
handler close the mir connection which should release all its video
buffers, then re-raise segv. Would it be of interest to have all mir
clients exhibit this behaviour by default? If so, should put this
behaviour in "mirclient"
If just for Qt, then Qtubuntu.
If unity8 crashes, there is the similar issue that it will hang until
apport releases it. Mir/QtMir could gain similar ability to release its
buffers before coredump, which would shrink the collected core. This
could again be a Mir task.
QtMir's ApplicationManager will need adjusting to allow new instance of
app to be launched, while the old instance is dumping core.

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?
