Bug Description

STEPS:
1. On a BQ device install the terminal and d-day tower defense
2. Open the terminal and run free -h
3. Open d-day and start the game playing
4. Flip back to the terminal and run free -h again
5. There should be about 21MB free
6. Put the phone to sleep
7. Now call the phone
8. As the dialer app is opened it looks like the oom killer kills the open apps which in turn triggers apport which then hog the cpu

EXPECT:
I expect to the able to answer the call with no issues

ACTUAL:
The phone can lock up completely making it impossible to answer the call, the call goes to answering machine and when the phone is able to be used you get the missed call notification.

I don't think unity8 has any role to play wrt apport launching.
also, apport shouldn't be launched for apps being killed for oom, only in cases where they crash.

It may happen though that apps crash when being killed if they're not properly coded?
