Well, then we would also have to track the DTMManager in XRTreeFrag, which
is already too bloated with member variables. Each instance could make a
new member of XPathContext... this might be the better choice. But a
bigger change than I want to make right now.
For right now, I just put in a c
Subject: Re: Stylesheet Reuse
Scott's diagnosis makes sense to me.
Simplest fix might be for each transform() call to allocate a new
DTMManager, so the late finalizers could negotiate with the old one without
any interaction with the new transformation.
Best fix might be to improve our scoping to eliminate the need for the

Ouch. Maybe I'll try runiing it on Linux and see if it reproduces. Sounds like
as, Joseph said, a timing problem.

Might be worth taking another look at the finalizer for XRTreeFrag. We had
a timing problem there since the finalizer does run in a second
