That fix provides the ability to take care of it.  It doesn't actually do 
anything in the parser so far.  We could replace adding/removing the dummy 
parser request with BlockOnload()/UnblockOnload() if we handle the Cancel() 
issue I mention in bug 294115.

I do find it odd that just using DummyParserRequest didn't work, though...  That 
makes me suspect that the other solution would have the same issues, frankly. 
If you want to check, you could ignore the Cancel() thing for now and just see 
whether you can BlockOnload()/UnblockOnload() and whether that works.

Just onload.

Create an HTML page such that the parser would get interrupted after all the 
data has been received from the network but before it's been parsed (simplest 
way is to interrupt very often, probably).  Then see whether onload fires too 
early (e.g. by having an inline <script> at the end of the document and an 
onload handler and seeing which one runs first).
