Process.daemon deadlock bug

[Sam Kottler]

There is a pretty severe bug that's probably a good candidate for backport to F20 and rawhide. The patch [1] reduces a potential deadlock with using Process.daemon. I can commit the patch and build a new version for the affected versions, just want to make sure people are on-board with pushing this into our packages until 2.1 final is released.
