New submission from Simon de Vlieger <simon at ikanobori.jp>:

When I have replaced sys.stdin with my own file-like object and I try to do a multiprocessing.Pool(processes=x) I get errors about sys.stdin not having a fileno or close method.

For at least fileno it is described in the docs (http://docs.python.org/library/stdtypes.html#file-objects) that if your object is not a real file you should not implement it.

This happens to me on Mac OS X, I will add the traceback a bit later as I am currently not on my Mac.
