In https://github.com/wilsonpage/gaia/commit/88373310a90755c462c2412c2a2bec1acaa6d588#diff-9abc58b23a8ea1bc557f1e69f21ceab4R103 Wilson said he'd change this to _fireArgs.

I don't feel strongly about that, but if he actually did that, then we're still missing some commits that should be in this patch.
