statistics from some cpus don't fit
Cpu statistics from time_in_state does not fit
in the data structures in ProcessState.java. The
time_in_state file eventually becomes larger than
the buffer of 256 bytes witch cause missing data
in the result or a NoMoreElementsException when
parsing the data.
The numger of cpu speeds can be larger than the
MAX_SPEEDS limit.
Solution
Make sure that the whole file gets read and increase
the MAX_SPEEDS that the system can handle.

Fix some crashes that are happening in the system process.
- 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.am.ActivityStack$1.handleMessage(ActivityStack.java:282)
at android.os.Handler.dispatchMessage(Handler.java:99)
at android.os.Looper.loop(Looper.java:137)
at com.android.server.ServerThread.run(SystemServer.java:603)
- If an invalid Uri object is sent to the system process it can crash because
the Uri class throws an assertion while unmarshalling. Change this to an
IllegalArgumentException so it gets sent back to the caller:
java.lang.AssertionError
at android.net.Uri$PathPart.readFrom(Uri.java:2224)

at dalvik.system.NativeStart.run(Native Method)
- 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
at android.app.ApplicationErrorReport$CrashInfo.<init>(ApplicationErrorReport.java:341)
at android.os.StrictMode$ViolationInfo.<init>(StrictMode.java:1978)

at com.android.server.am.ActivityManagerService$AThread.run(ActivityManagerService.java:1302)
(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:
