Yes, it is potentially a problem. Saxon won't read and parse the document
until the document() function is executed, but it will then hold the tree in
memory - it has to, because if document() is called again with the same URI,
it has to return the same tree. So the garbage collector won't get any
chance to clear up. Perhaps an explicit free() mechanism is needed (but that
gets into questions of sequence of execution and side-effects).
