  Patch #1583 by Adam Olsen.

  This adds signal.set_wakeup_fd(fd) which sets a file descriptor to
  which a zero byte will be written whenever a C exception handler runs.

  I added a simple C API as well, PySignal_SetWakeupFd(fd).

  Patch #1549 by Thomas Herve.
  This changes the rules for when __hash__ is inherited slightly,
  by allowing it to be inherited when one or more of __lt__, __le__,
  __gt__, __ge__ are overridden, as long as __eq__ and __ne__ aren't.

 * The :mod:`sets` module has been deprecated; it's better to 
   use the built-in :class:`set` and :class:`frozenset` types.
 
+* Integrating signal handling with GUI handling event loops 
+  like those used by Tkinter or GTk+ has long been a problem; most
+  software ends up polling, waking up every fraction of a second.  Thi
+  The :mod:`signal` module can now make this more efficient.
+  Calling ``signal.set_wakeup_fd(fd)`` sets a file descriptor
+  to be used; when a signal is received, a byte is written to that 
+  file descriptor.  There's also a C-level function,
+  :cfunc:`PySignal_SetWakeupFd`, for setting the descriptor.
+
+  Event loops will use this by opening a pipe to create two descriptors,
+  one for reading and one for writing.  The writeable descriptor
+  will be passed to :func:`set_wakeup_fd`, and the readable descriptor
+  will be added to the list of descriptors monitored by the event loop via
+  :cfunc:`select` or :cfunc:`poll`.
+  On receiving a signal, a byte will be written and the main event loop 
+  will be woken up, without the need to poll.
