I should clarify that although the main.c in this example has argc and 
argv, when I deploy my C extension as a .so file, there is no main() 
method as far as my code is concerned.  The Verilog simulator owns the 
main() method and my C extension has *no* way of accessing the argc and 
argv passed to that main() method.

For this reason, I did not pass the argc and argv from main() to the 
body of the gRubyThread (because that is the real-life scenario of this 
simple example).  And since ruby_sysinit() requires an argc and argv, I 
am forced to fabricate them inside the body of gRubyThread.
