I thought Enrica had fixed this a while ago... Maybe it has regressed or that we need to make it even faster?

1. Open any page with a decent textarea
2. Paste a text about 1MB or more
3. wait
What is the expected result?
a fast reaction
What happens instead?
Browser stalls for some time overproportionally depending on text length it seems. This takes much longer than on competing browsers eg. firefox even though the overall experience is a lot faster on chromium on my system.

I'm attaching a sampling result with Safari.
How to reproduce:
1. Open repro.html in Comment 4 with Safari + Debug-built WebKit
2. Focus on the textarea
3. ⌘-A, ⌘-C
4. Press Down cursor to go to the end of the editing area
5. Start sampling
6. ⌘-V
7. Wait for re-blinking the caret
8. Stop sampling
