I've found some files that take too long to convert to be reasonable. From one of them (the Project Gutenberg edition of The Brothers Karamazov), I could create this test file:
If I remove almost anything in the CSS styles, it converts instantly, but as it is, it remains some minutes at 100% CPU load until I kill the process.

<p>The old man fairly fluttered with joy, as though nothing more comforting
could have been said to him. In his delight he seized <span>[pg 154]</span>

his eyes.</p>
