a long word in the source, that has no chars that would allow a visual line break, will cause mozilla to use insane amount of memory and cpu time to render the page.

Similar issues:

Reproducible: Always

Steps to Reproduce:
1. open the url
2. increase the length-parameter by 1024 each try
3. see how mozilla uses a large amount of memory eg: when the value is 8096

Can you retest with the latest trunk build, for I think I can't reproduce it anymore in trunk builds.
