def recv_stderr_ready(self):
return self.in_stderr_buffer.read_ready()<EOL>
Returns true if data is buffered and ready to be read from this
channel's stderr stream.  Only channels using `exec_command` or
`invoke_shell` without a pty will ever have data on the stderr
stream.

:return:
    ``True`` if a `recv_stderr` call on this channel would immediately
    return at least one byte; ``False`` otherwise.
