/**
 * File systems maintain per-FileObject directory cursor information. When multiple threads do queries using the same FileObject,
 * access to the per-FileObject structure is single threaded to prevent corruption of the cursor state.
 * This flag tells the file system to not update per-FileObject cursor state information thus allowing multiple threads 
 * to query in parallel using the same handle. It behaves as if SL_RESTART_SCAN is specified on each call. If a wild card pattern
 * is given on the next call, the operation will not pick up where the last query ended. 
 * This allows for true asynchronous directory query support. Not all file systems support this flag.
