Good call.   I just slapped a nil onto startAnimation and stopAnimation,
and it's nice and neat now.  I don't even need those hanging underscores
anymore, which suggests to me that the reason I needed them was possibly
that I was missing the argument.

It worked just doing the calls from the secondary thread, but just in
case, I've switched it to use
performSelectorOnMainThread_withObject_waitUntilDone, and it's still
working great.

Thank you very much.  Without this threading my little XHTML validator
would be unpleasant to use, with its frozen UI during the checking and all.

Thanks again!
