+class _allow_interrupt(object):
+    """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 "console 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.
