after having loaded ca. 50% and page displays, mozilla begins to hang using 
100% cpu and does not respond until manually killed
I can confirm this bug with w2k build 2001012304

Confirmed.  I've been seeing intermitten hangs for the last 2 or 3 days
(starting 20010123, I think), but this is the first URL that consistently causes
the problem.
I've created a smaller testcase at:
http://homepages.tig.com.au/~mcgarry/moz/66792/66792.l.html
Note that the page does not freeze mozilla indefinately, only for a while (which
is why the testcase isn't smaller, as the freeze becomes less noticable on my PC).
The pauses seem to occur when the images start coming in (the images have no
width attribute set in html).
With the images removed, there is no noticable lag:
http://homepages.tig.com.au/~mcgarry/moz/66792/66792.l.noimages.html
Also with images, and no outer-lying table, there is no noticable lag either:
http://homepages.tig.com.au/~mcgarry/moz/66792/66792.l.notable.html

I hope this helps :)

Looks like list numbering performance.

I'll take a look. I have some related list number bugs.

So there are a couple problems here. This web page is basically a big, one-cell
table. Inside are about 32 images, most of which have no width/height
information. The page initially loads pretty quickly, but then goes off into
space once the image width & height information arrives and those frames get
reflowed. There are also nested <font> tags which exacerbate the problem.

karnaze: could you give this page a quick try with your new table reflow magic?
I'm wondering if that will make things better...

I tried the new table reflow changes and it still appears to hang on attachment 
#2 [review] (I gave up after about 2 minutes). The problem may be an infinite loop in the 
block code. In the debugger, every time I broke, I saw the following stack, and 
it was always the same table cell frame!
