Summary: 1==float('nan')

Initial Comment:
In python 2.3.1 on Linux/x86, X==float('nan') evaluates
to True given any number value for X.  I admit to not
knowing much about IEEE arithmetic.  But, is this Kosher?

Man, that's strange (I see the same behaviour on my redhat 9
box with 2.3.3).

I don't have time to dig right now, but if you want to,
playing with equivalent C programs would be a very good start.
