Initially we're taking a cautious approach: using multithreading 
automatically where we're pretty confident it will usually give a 
benefit (xsl:result-document, fn:collection()) and allowing it to be 
invoked manually in cases where we think it's likely to incur more cost 
than benefit in a significant number of cases (xsl:for-each, 
xsl:apply-templates). Hopefully the decision-making will become more 
sophisticated as we gain experience and gather user feedback.
