Fix up Freeze when clicking clean button (1/2)
Here is the Race condition. Background thread calls updateStatus() every 500ms. updateStatus() calculates information & updates various labels. On clicking Clean button, updateStatus() is called at the end of operation which causes Race Condition for labels. To avoid this race condition when we lock respective label, Main thread blocks forever & Application freezes. So just ignore Race Condition.
