Torture test

This is a gzip-compressed torture test.  WARNING: It will expand to over 1 MB
in size when uncompressed!

Basically, this is a 1 MB file with a missing </title> tag that causes the
tokenizer to consume the entire document.

With my current fix (patch coming soon), the page will render in about 12
seconds on a 1.5 GHz PB G4 with 1 GB RAM.  It spends 2-3 seconds consuming the
document looking for </title> (spinner pauses during this time), then backs up
and reparses with no special handling of the title.

Firefox on the same PB G4 takes a few MINUTES to parse the file, but
eventually finishes and inserts the missing </title> tag.  MSIE 6 on a 1.7 GHz
IBM ThinkPad T42 with 2 GB RAM takes at least twice as long as Firefox, and
just stops parsing after it reaches the end of the document with no </title>
