The event loop can be broken up into a multiplexer (the part
responsible for notifying us of I/O events) and the event loop proper,
which wraps a multiplexer with functionality for scheduling callbacks,
immediately or at a given time in the future.

Whenever a public API takes a callback, subsequent positional
arguments will be passed to the callback if/when it is called.  This
avoids the proliferation of trivial lambdas implementing closures.
Keyword arguments for the callback are not supported; this is a
conscious design decision, leaving the door open for keyword arguments
to modify the meaning of the API call itself.

        Create a streaming transport connection to a given Internet host and
        port: socket family AF_INET or socket.AF_INET6 depending on host (or

        a callable returning a protocol instance.

        Return the total number of bytes which were sent.

        The method uses high-performance os.sendfile if available.

        file must be a regular file object opened in binary mode.

        offset tells from where to start reading the file. If specified,
        count is the total number of bytes to transmit as opposed to
        sending the file until EOF is reached. File position is updated on
        return or also in case of error in which case file.tell()
        can be used to figure out the number of bytes
        which were sent.

        fallback set to True makes asyncio to manually read and send
        the file when the platform does not support the sendfile syscall
        (e.g. Windows or SSL socket on Unix).

        Raise SendfileNotAvailableError if the system does not support
        sendfile syscall and fallback is False.

        This is called when an exception occurs and no exception
        handler is set, and can be called by a custom exception
        handler that wants to defer to the default behavior.

        This default handler logs the error message and other
        context-dependent information.  In debug mode, a truncated
        stack trace is also appended showing where the given object
        (e.g. a handle or future or task) was created, if any.
