Comment (by jdemeyer):
Note the difference of a factor 20 between the following:
{{{
sage: b = ZZ(1); a = Infinity; timeit('a < b', repeat=20, number=10^4)
10000 loops, best of 20: 11.7 µs per loop
sage: b = ZZ(1); a = QQ(2); timeit('a < b', repeat=20, number=10^4)
10000 loops, best of 20: 681 ns per loop
}}}
A proper Cython implementation of `Infinity` should match the speed for
`QQ`.
