  Thanks for pointing this out.  The stream classes
look really cool.

  So I replaced my bad 'while True' blocking code with
the following:

        filestream = stream.FileStream(file)
        dest = os.path.join(SAVEDIR,filename)
        destfile = os.fdopen(os.open(dest,
            os.O_WRONLY | os.O_CREAT | os.O_EXCL,
            0644), 'w', 0)
        stream.readIntoFile(filestream, destfile)

  And this works great -- but only for files smaller
than 10M.  It looks like files >10M still produce the
hang -- same behavior as before.

  I'll file tickets for both of these, to try to stop
cluttering the mailing list with these issues.

Thanks,
Lenny
