[issue26228] pty.spawn hangs on FreeBSD 9.3, 10.x

[Geoff Shannon]

I took a shot at fixing this in a smaller more targeted patch.  I think this should still solve the major issue of pty.spawn hanging on platforms that don't raise an error.  In addition, pty.spawn should now _ALWAYS_ return the terminal to the previous settings.
