Right way to io.open(...) an existing file object in Python 2.7?

I'd like to take advantage of the seekable() method of io.IOBase with
existing open file objects, especially the standard in/out/err file
objects. I know on Linux I can just do this:
fp = io.open("/dev/stderr")
but that's kind of cheating. File objects in Python 2.7 aren't created
using the io module's machinery. Assume somewhere else a plain old
open file object, for example:
fp = open("/some/path/to/nowhere.txt", "w")
and wanted to treat fp as if it had been opened with the io module
machinery, I don't see any sort of "fdopen" or "freopen" equivalent
mentioned in the io module documentation. Is this possible in a clean
way?
Thx,
Skip
