/**

 * the existence of those directories if the mkdir fails at any point (since
 * that directory might have just been created by some other process).
 * If both mkdir() and the exists() check fails for any seemingly 
 * non-existent directory, then we signal an error; Sun's mkdir would signal
 * an error (return false) if a directory it is attempting to create already
 * exists or the mkdir fails./* www  . j a  va  2  s  .  co m*/
