No. Because sorting could happen a lot.
Also, your patch brings wrong assumption that every XslTransform
must be immutable, even when msxsl:script is involved (and I don't
think we welcome "x is thread safe" "y is not" sort of complication).
You are anyways standing on wrong premise anyways. Create multiple
XslTransform for each thread. Since newobj happens a lot, it shouldn't
be a big problem (for you at least).
