Yeah Kevin should have the final say on this since he's seen more of the

I looked this up and the closest "answer"
I could find was the examples and explanation here:
<http://www.w3schools.com/jsref/met_doc_write.asp>

From this it looks like html is shoved into the document prior to parsing then
the document is reparsed in the loading case.
In the post-loading case it looks as if we need to replace everything in the
document with the document.write output. Same goes for document.writeln I guess.
