Hey Daniel,
The bigger issue for us is mostly the fact that Decimal.__hash__ us calling Decimal.__int__ and not because we want an integer/long version of a very large Decimal. We do not actually cast the decimal into an int/long explicitly. I wouldn't have any issues if Decimal.__int__ remained as it is, but I think it would be a good idea for Decimal.__hash__ to do something differently. Probably something that is fast and simple, such as hash( self.as_tuple() ), self being a Decimal of course.
Our project is a CAS and we use Decimal for our real number class. I happened to run into this issue when I was implementing approximation of log(x) for extremely large/small values of x. I just started keyboard bashing numbers and behold, Decimal crashed on me :)
