[issue4233] open(0, closefd=False) prints 3 warnings

[Amaury Forgeot d'Arc]

New submission from Amaury Forgeot d'Arc <amauryfa at gmail.com>:

This happens with a recent py3k build:

>>> x = open(0, closefd=False)
>>> del x
C:\dev\python\py3k\lib\io.py:1461: RuntimeWarning: Trying to close 
unclosable fd!
  self.buffer.close()
C:\dev\python\py3k\lib\io.py:389: RuntimeWarning: Trying to close 
unclosable fd!
  self.close()
__main__:1: RuntimeWarning: Trying to close unclosable fd!

Also, there are no unit test for closefd.
