Re: NSSpeechSynthesizer leaking

Hmm? In speechSynthesizer: didFinishSpeaking: it says: [inSender 
release].

BTW, I also tried creating an autoreleased version of 
NSSpeechSynthesizer instead of releasing via the delegate message. 
Either way though the NSSpeechSynthesizer will get dealloc'd, but not 
clean up after itself properly.

I will probably work around this by creating a single 
NSSpeechSynthesizer and reusing it as needed, but I shouldn't have to.
