Ah, that's what #74 means.

  On the objc side or both sides? I spent some amount of time trying  
to figure out
how to feed ruby stack traces into the Instruments.app sample  
instrument, but there's really no docs on how that stuff works. I  
originally thought I could just slap together some dtrace scripts, and  
ta-da! I'd have ruby sample runs. No such luck, as far as I could  
tell, you can do it for Java, but not Ruby.

  On that note, would it be useful for me to make a Trac request for  
such a feature?
