Assuming you're using one of the rb_str_new family of functions to 
create Ruby String objects from C strings, Ruby makes a copy of the C 
string in Ruby-managed memory. In general Ruby objects are always in 
Ruby-managed memory unless you're wrapping one of your own C structures 
into a Ruby object with Data_Wrap_Struct.
