fobj.flush()
File objects use buffered IO and by changing from using file
objects to file descriptors half way through the buffer
could be in any state. You need to flush() to force it to
the file before doing anything weird.
As was said in a recent thread, mixing file objects and
file descriptors is a bad idea. The OS can get confused,
let alone the programmer!
> os.close(fp)
And especially if you open the file as one thing and
close it as another! Be consistent, either work with
file descriptors throughout or file objects. If you
must mix them be prepared for strangeness.
