I see at least two options:

  - Use the macros in rubyio.h to wrap the FILE* that you already have.
    This is "cheating" the ruby API a bit, since you'd be accessing
    structures that I don't think Matz intended for us to access
    directly.

  - Use IO#fdopen to re-open the pipe once it is opened.
