[issue13625] multiprocessing.reduction gives OSError: [Errno 9] in 2.7.2

Two patches have recently modified this part of the code:
http://hg.python.org/cpython/rev/d4d9a3e71897
http://hg.python.org/cpython/rev/cd15473a9de2

I'm unable to reproduce the problem on Linux 3.1.0 x86 with branch 2.7 (for those who would like to try, you just need to connect to port 9090/tcp, e.g. with netcat). Also, none of the buildbots complains, so this is rather surprising.

Yaşar, could you test to find out which patch introduced the problem ?
Also, could you provide the result of:
$ strace -f -e network,dup,dup2,close ./python ~/multiprocesssockserv.py

when you run your test?

Do you get the error upon the first connection?
