Would it make sense to change the Unicode object to use pymalloc, and to change the UTF-8 codec to count the bytes if the shortest possible output would fit in a pymalloc block? (I guess this means that the length of the Unicode string should be less than SMALLREQUESTTHRESHOLD - currently 256.)

Given my measurements, that would make sense. I suspect that counting small strings is quite efficient, so that the overhead of iterating over the string twice hides in the noise of additional invocations.
