[closure-devel] forever stirring the tag soup

[Ben Hyde]

Parsing a github project page takes forever.

> (setf sgml::*parse-warn-level* 5) 
> (let ((page (drakma:http-request "https://github.com/rss-sync/corpus"))) (handler-case (bt:with-timeout (10) (chtml:parse page (make-instance 'hax:default-handler))) (condition (c) c)))
#<bordeaux-threads:timeout #x302009C80C6D>

Multiple div's appearing in a THead element are the root cause.

> (setf sgml::*parse-warn-level* 0)
0
> (chtml:parse "<table><thead><div>a</div><div>b</div></thead></table>" (make-instance 'hax:default-handler))

So far, I'm not clever enough to fix this.
