It has been cast in both lights previously.  Seems to boil down to it being
undocumented, implementation-specific behavior.  There is nothing
guaranteeing that it works for any implementation, and Jython is known to
behave somewhat differently for such cases.

Note also that you are assigning x to the return value of write(), not the
file handle returned by open().
