/**
 * NIO version of FSDirectory.  Uses FileChannel.read(ByteBuffer dst, long position) method
 * which allows multiple threads to read from the file without synchronizing.  FSDirectory
 * synchronizes in the FSIndexInput.readInternal method which can cause pileups when there
 * are many threads accessing the Directory concurrently.  
 *
 * This class only uses FileChannel when reading; writing
 * with an IndexOutput is inherited from FSDirectory.
 * 
 * Note: NIOFSDirectory is not recommended on Windows because of a bug
 * in how FileChannel.read is implemented in Sun's JRE.
 * Inside of the implementation the position is apparently
 * synchronized.  See here for details:

 * http://bugs.sun.com/bugdatabase/view_bug.do?bug_id=6265734
