- When shutting down, if the screen goes to sleep there is code
that tries to do a notifyAll without holding the lock:
java.lang.IllegalMonitorStateException: object not locked by thread before notifyAll()
at java.lang.Object.notifyAll(Native Method)
at com.android.server.am.ActivityStack.checkReadyForSleepLocked(ActivityStack.java:776)

at com.android.server.ServerThread.run(SystemServer.java:603)
- If an invalid Uri object is sent to the system process it can crash because
the Uri class throws an assertion while unmarshalling. Change this to an
IllegalArgumentException so it gets sent back to the caller:
java.lang.AssertionError

- StrictMode can try to access the first index in the stack crawl of a stack crawl
array of length 0. Not sure why this happens, but make the code more robust:
java.lang.ArrayIndexOutOfBoundsException: length=0; index=0

(Also fix this code to not cause strict mode to trigger at all, because there is
no need, because this is just reading stuff from /proc.)
- The system seems to crash during boot if it thinks it needs to rotate
the screen, when it is trying to take the freeze snapshot way too early.
There is no need to freeze the screen during boot or if the screen is off:
