The following code copies data, whereas the copy can be avoided using a memory view:

chunk = self._input[self._input_offset:self._input_offset + _PIPE_BUF]
self._input_offset += os.write(key.fd, chunk)

It should be replaced with:

input_view = memoryview(self._input)
...
chunk = input_view[self._input_offset:self._input_offset + _PIPE_BUF]
self._input_offset += os.write(key.fd, chunk)


This issue is a reminder for one of my comment of issue #18923.
