Dump the phone process stack (as well as the system process) on watchdog reset.

            ArrayList pids = new ArrayList();

            pids.add(Process.myPid());

            if (mPhonePid > 0) pids.add(mPhonePid);

            File stack = ActivityManagerService.dumpStackTraces(pids);

            // Give some extra time to make sure the stack traces get written.

            // The system's been hanging for a minute, another second or two won't hurt much.

            SystemClock.sleep(2000);

            mActivity.addErrorToDropBox("watchdog", null, null, null, name, null, stack, null);

            // Only kill the process if the debugger is not attached.
