I took a look and ran through some snapshots. I remembered a discussion last month regarding the propogation of socket errors to dup'd sockets. It seems the patch (or something commited at the same time) broke this as on the 4/18 snapshot all works well and it breaks on the 4/24 snapshot which is the same one that got that last bit patched. I do not know if the patch was ever tested as the OP of that thread never responded from what I can tell. I tested on x86 only as my x86_64 install is running May 23rd snapshot and for some reason trying to go to an older snapshot resulted in an unusable install so I reinstalled my x86 one in order to test the older snapshot releases.
