Shouldn't we CFRelease value after this copy? Maybe use RetainPtr here?

Nice! Do you plan to adopt this for sync XHR, or would you like us to keep receiving reports about those?

I talked to Gavin about doing it - it's definitely something we should do. Same thing for window.print.

I think this one line does the same thing as the above four lines of code.

    return adoptCF(valuePtr) == kCFBooleanTrue;
