-    """Utility for fixing CTRL-C events on Windows.
-
-    On Windows, the Python interpreter intercepts CTRL-C events in order to
-    translate them into ``KeyboardInterrupt`` exceptions.  It (presumably)
-    does this by setting a flag in its "control control handler" and
-    checking it later at a convenient location in the interpreter.
-
-    However, when the Python interpreter is blocked waiting for the ZMQ
-    poll operation to complete, it must wait for ZMQ's ``select()``
-    operation to complete before translating the CTRL-C event into the
-    ``KeyboardInterrupt`` exception.
-
-    The only way to fix this seems to be to add our own "console control
-    handler" and perform some application-defined operation that will
-    unblock the ZMQ polling operation in order to force ZMQ to pass control
-    back to the Python interpreter.
-
-    This context manager performs all that Windows-y stuff, providing you
-    with a hook that is called when a CTRL-C event is intercepted.  This
-    hook allows you to unblock your ZMQ poll operation immediately, which
-    will then result in the expected ``KeyboardInterrupt`` exception.
-
-    Without this context manager, your ZMQ-based application will not
-    respond normally to CTRL-C events on Windows.  If a CTRL-C event occurs
-    while blocked on ZMQ socket polling, the translation to a
-    ``KeyboardInterrupt`` exception will be delayed until the I/O completes
-    and control returns to the Python interpreter (this may never happen if
-    you use an infinite timeout).
-
-    A no-op implementation is provided on non-Win32 systems to avoid the
-    application from having to conditionally use it.
-
-    Example usage:
-
-    .. sourcecode:: python
-
-       def stop_my_application():
-           # ...
-
-       with allow_interrupt(stop_my_application):
-           # main polling loop.
-
-    In a typical ZMQ application, you would use the "self pipe trick" to
-    send message to a ``PAIR`` socket in order to interrupt your blocking
-    socket polling operation.
-
-    In a Tornado event loop, you can use the ``IOLoop.stop`` method to
-    unblock your I/O loop.
