open testcase... 
this will take quite a while (100% load) = regression 1
select all text in the textarea and press copy
now press paste and see the load go up
wait 5-10 secs, depending on your system and the text is pasted

this worked fine and instantaneously before

I wasn't able to reproduce this as described on my clean install/clean profile of Mozilla/5.0 (Windows;;; en-US; rv:1.8.1a3) Gecko/20060704 BonEcho/2.0a3, on a P3-1.2ghz PC w/640mb ram.

However, I can reproduce the other reported bug (https://bugzilla.mozilla.org/show_bug.cgi?id=343314) in the testcase window.

We're spending tons of time in nsRange::IsPointInRange, called by mozInlineSpellChecker::IsPointInSelection. I think this is a previously existing and known issue. You only see it now because before bug 339066 was fixed, pasting didn't get spellchecked properly at all.
