--- NEW FILE: TimeoutSocket.py ---
"""Based on code from timeout_socket.py, with some tweaks for compatibility.
   These tweaks should really be rolled back into timeout_socket, but it's
   not totally clear who is maintaining it at this point. In the meantime,
   we'll use a different module name for our tweaked version to avoid any
   confusion.

   The original timeout_socket is by:

	Scott Cotton <sc...@ch...>
	Lloyd Zusman <lj...@as...>
	Phil Mayes <pm...@ol...>
	Piers Lauder <pi...@cs...>
	Radovan Garabik <ga...@me...>

"""Utilities for handling IEEE 754 floating point special values

This class implements constants and functions for working with IEEE754
double-precision special values.  It provides constants for NaN (Not a
Number), NegInf (Negative Infinity), PosInf (Positive Infinity), and
Inf (also Positive Infinity), as well as functions to test for these
values.

The code is implemented in pure python by taking advantage of the
'struct' standard module.  Some efficiency could be gained by
translating the core routines into C.
