Ok I took a detailed look at _bytesio.c.
In write_bytes() there is the following resizing logic:
if (self->pos + len > self->string_size) {
if (resize_buffer(self, self->pos + len) < 0)
return -1;
}
Replacing `self->string_size` with `self->buf_size` should avoid some
spurious reallocations.
For some reason, using the help() function on a BytesIO instance does
not display the class help.
Overall, the new module looks fine. I can't say anything about the io.py
or _fileio.c fixes.
