[issue1407] [performance] Too many closed() checkings

[Amaury Forgeot d'Arc]

Amaury Forgeot d'Arc <amauryfa at gmail.com> added the comment:

I reproduce almost the same output.
"function.closed" often come in pair, because TextIOWrapper.closed is a
property which delegates to self.buffer.closed

I think that the first check in TextIOWrapper.write() is not necessary:
self.buffer.write(b) will also check for "self.buffer.closed", and there
is not much code in-between. The only side-effect is the decoder state.
