That's great news. These things are really nasty. lxml 2.0 has had a bit of
internal reengineering, which also lead to a couple of structural fixes. Some
of these might find their way back into 1.3 one day, although I'd have to look
through the (long list of) changes first. I'm more concerned about getting 2.0
stable for the final release now.

What might actually have done the trick here is the conservative
"copy-if-foreign" XSLT change, which now copies the stylesheet if it was
created in a different thread. This is definitely sub-optimal, but I'll look
into that later. As usual: 1) make it work, 2) make it fast (if necessary).

You're welcome.
