| * it keeps running and locking again it can prevent the main thread from |
| * acquiring its lock for a long time... sometimes even > 5 seconds |
| * (leading to an ANR). |
| * |
| * Dalvik will promote a monitor to a "real" lock if it detects enough |
| * contention on it. It doesn't figure this out fast enough for us |
| * here, though, so this little trick will force it to turn into a real |
