I am trying to understand the issues related to bug 18333 (XML content 
sink not incremental).

Is http://www.mozilla.org/newlayout/doc/threading.html still accurate? 
The tag soup parser and expat still run in the UI thread, right? (Seems 
counter-intuitive to me. Was this done in order to accommodate the old 
Mac OS?) 

When expat is parsing, does the UI thread pump chunks of data to 
XML_ParseBuffer so that the event loops processes events in between the 
XML_ParseBuffer calls?

Is there any particular reason why the XML content sink does not force a 
reflow once in a while if the parsing takes a long time?
