Comment on attachment 587651 [details] [diff] [review] Remove obsolete speculation code It makes me sad to review this, but it's time to move on. That being said, the Holder class (just above nsSpeculativeScriptThread) can be deleted as well.
Thanks. Landed with Holder removed, too. https://hg.mozilla.org/integration/mozilla-inbound/rev/39e49fcaed22
