> {{CopyOnWriteDirectory}} makes use of working set (introduced with OAK-3110) to notify the {{CopyOnReadDirectory}} that those files are in use. This would ensure that CoR dir does not consider such files as garbage. 
> This set gets cleared when CoW dir closes cleanly. However in case it does not close cleanly such a state would not be cleared. To handle such cases we should clear the working set upon construction of CoW dir as there can be only one writer by design
