`io.TextIOWrapper.write()` returns the length of the passed string instead of the actually written number of characters. % python -u -c "import sys; print(sys.stdout.write('x'*4294967296), file=sys.stderr)" \| wc -c 4294967296 2147479552 So the possibility "users of `io.TextIOWrapper` call `write()` until all characters have been written" would not be sufficient.
