Handle closed sys.__stdin__, for multiprocessing

Buggy code in python's multiprocessing/process.py closes sys.stdin and
reassigns it to open(os.devnull), but fails to update the corresponding
__stdin__ reference. So, detect that case and handle it appropriately.
The buggy code is visible in http://hg.python.org/lookup/r73708.

This may be useful for using threads to handle blocking IO with Jython,
since Jython lacks the fcntl module which is needed for non-blocking IO
(see http://bugs.jython.org/issue1074).
