Comment(by bgoodri):
Okay, actually my patch does not work so well for the example that
motivated it. I am now attaching a test.ginsh file that defines a rational
expression, substitutes a variable with another big rational expression,
calls normal and quits. The GiNaC shell finishes in about 1 minute on my
laptop (in a shell execute: "time ginsh test.ginsh"). But after applying
my patch to sage and then trying to do the equivalent thing via test.sage,
it can go for hours without finishing. So, something is badly wrong,
possibly my patch.
