-Create a subprocess
--------------------
+Operating system support
+------------------------
+
+On Windows, the default event loop uses :class:`selectors.SelectSelector`
+which only supports sockets. The :class:`ProactorEventLoop` should be used to
+support subprocesses.
+

+
+Create a subprocess: high-level API using Process
+-------------------------------------------------
 
 .. function:: create_subprocess_shell(cmd, stdin=None, stdout=None, stderr=None, loop=None, limit=None, \*\*kwds)
 
    Run the shell command *cmd* given as a string. Return a :class:`~asyncio.subprocess.Process`
    instance.
 
+   The optional *limit* parameter sets the buffer limit passed to the
+   :class:`StreamReader`.
+
    This function is a :ref:`coroutine <coroutine>`.
 
 .. function:: create_subprocess_exec(\*args, stdin=None, stdout=None, stderr=None, loop=None, limit=None, \*\*kwds)
 
    Create a subprocess. Return a :class:`~asyncio.subprocess.Process` instance.
 
+   The optional *limit* parameter sets the buffer limit passed to the
+   :class:`StreamReader`.
