Message 78420 - Python tracker

Attached: quick and dirty test to check if the standard input is 
buffered or not. My short test program works with python2.5 and py3k 
trunk without the -u command line option. So changing sys.stdin buffer 
is not really important.

About the wrong name, I opened a separated issue: #4762, 
PyFile_FromFd() doesn't set the file name.
