I managed to create a hang in a locally-built debug build of WebKit r15648
while editing a textarea, again related to replying to Bug 8278 Comment #5.  I
was smart enough to capture a Shark trace of the activity, which only shows
four methods (if I remember correctly) being called repeatedly.

What I remember when hitting this hang:

1. Just did the steps in Bug 10143 to reproduce it.
2. Moved the cursor up to the first of three blank lines created between the
two quoted paragraphs.  (Don't know if I used the arrow keys or the mouse to do
this.)
3. Tried to insert more text by hitting Enter (or maybe another printable
character?), then the hang started.

Will attach the Shark profile next.
