SF patch #907403: Improvements to cStringIO.writelines()
The writelines() method now accepts any iterable argument and writes
the lines one at a time rather than using ''.join(lines) followed by
a single write. Results in considerable memory savings and makes the
method suitable for use with generator expressions.
