Yes. Actually, now that I look at it, EH isn't working at all with the 
interpreter on PowerPC. _Unwind_RaiseException() is returning 
_URC_NO_REASON and libgcj aborts. But thats another problem.

I see it hanging on the read() call at natPosixProcess.cc:278. Seems 
like Runtime.exec() always fails under the interpreter (works fine from 
compiled code). Weird indeed.

public class Test
{
  public static void main(String[] args) throws java.io.IOException
  {
    Process p = Runtime.getRuntime().exec("ls");
  }
}
