/**
 * The logSync() method in FSEditLog is unsynchronized whiel syncing

 * /*from  w w w  .  ja v a  2s.  c  o  m*/
 * This replicates the following manual test proposed by Konstantin:
 *   I start the name-node in debugger.
 *   I do -mkdir and stop the debugger in logSync() just before it does flush.
 *   Then I enter safe mode with another client
 *   I start saveNamepsace and stop the debugger in
 *     FSImage.saveFSImage() -> FSEditLog.createEditLogFile()
 *     -> EditLogFileOutputStream.create() ->
 *     after truncating the file but before writing LAYOUT_VERSION into it.
 *   Then I let logSync() run.
 *   Then I terminate the name-node.
