- File descriptors produced by dup() or dup2() now work exactly like

the original file descriptors they are duplicates of. I modified the
  function which maps file descriptor numbers to file descriptor
  table entries to return the table entries of the original files.

- In the thread-safe library, duplicated stdin/stdout/stderr
  descriptors now work like the "real" ones. This is true even if
  the "real" ones were closed and only their former aliases remain.
