Yup.

I'd back it out.  There's more to consider here than just whether "it's a
bug":  like also the Windows file.truncate() change, this replaced the
entire implementation of a feature with a new one using a different
approach.  I've got little fear of doing that for 2.3, because the new
implementation(s) will go thru alpha, beta, etc releases before becoming
"real".  For a bugfix release it's much riskier, as there's no way I can
swear that, e.g., there's no quirk on Windows ME (or XP, or ...) that might
cause the new implementation(s) to fail badly there.
