Ah, the problem is that the ruby code is being executed on a  
secondary NSThread. Unfortunately, Ruby is not thread-safe with  
respect to OS-level threads (which an NSThread is).

Ruby checks from time to time that the stack has not overflowed, and  
since the non-main thread will have a different area of memory for  
its stack than the main thread, Ruby thinks a stack overflow has  
occurred.

I'm afraid that there's probably no good way to work around this at  
the moment. It may be possible to get RubyCocoa running with Sydney  
[1], which apparently gives OS-level thread support. Do let us know  
if you give that a shot.

Sorry I don't have better news for you
Cheers
Jonathan
