Great that a solution was found at last.  But to be honest I don't
understand why my patch (the second one) is not good.  Why is it preferable
for libraries to provide their own file descriptor?

Are people concerned about the overhead of always creating a pipe even it
may not be used?
Always creating a pipe would at least avoid the need for any "coordination"
between PyGTK and Twisted.
