While I don't care all that much about performance on windows, it is a
little sad that it took this long to fix something so simple. Consider
this exchange, as a further example of our lack of concern here:

ISTM that we don't even care about Windows performance to a minimal
degree. Hopefully, the ICU stuff Peter Eisentraut is working on will
level the playing field here a little bit, if only as an accidental
side-effect.
