[issue7401] os.write and os.close on pipe from separate threads hangs on Mac OS X

I agree with martin, this is probably an OS bug. 

BTW. I can confirm that the issue occurs on OSX 10.6 as well (using the 
binary 2.6.4 installer on the python.org website).

I might get around to writing a C equivalent of the script in the future, 
but wouldn't mind if someone else did that work.  Such a script would 
pinpoint if the problem is in the OS or Python, and if it is in the OS it 
would allow filing a clear bug report at Apple.
