I checked one example on a 32-bit system (you have a 64-bit?)), because I was afraid pessimization because of a lack of registers. str.find() is faster than str.rfind(), but the patch makes it even faster. But I would like to see the script and the results of benchmarking of the 1/2/3/20-character ascii/ucs1/ucs2/ucs4-substring in ascii/ucs1/ucs2/ucs4-string, in all possible combinations. May be, such benchmark scripts already exist?
