certainly be wise to pick a larger limit, possibly target-dependent.
One other approach is to do a timing analysis which shows that in practice
the limit where the loop goes infinite cannot be reached. This may work in
the 64-bit case, unfortunately modern machines have got so blithering fast
that it is unlikely you can apply this in the 32-bit case.
