BuildID:    0.9.9

When trying to "enter" one of the delphi forums (tried multiple instances, and
the same thing happens), mozilla appears to hang.   The process will use all
available CPU on the the system and given time will consume all memory on the
system.  Stracing the proess shows it constantly calling brk.  

I can reproduce this at will (sigh) an will be happy to help.

Reproducible: Always
Steps to Reproduce:
1. Login to delphi forums (need to create an account)
2. Select a "forum" ... I have seen this on "Camp Bob" and others
3. Select a "thread" inside that forum.  ... Bug will now occur.

Looking at the strace, the last thing we see before the brk loop I see a very
long html page (37k) that starts off with

If you save the page locally, does it still hang?  If so, could you attach the
page here?

Please try a newer (nightly) build, too.

When loading parts of the frameset from local disk (saved via netscape 4.7) I
did not get the hang.

When fixing up the frameset to load local disk copies I did not net the hang.

And I cannot see that bug with Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US;
rv:0.9.9+) Gecko/20020324 build.

Seems to be a linux related bug. Strange !
