	* A problem has been found with QtRuby when it is run with Ruby 1.9.1
	  and GC.stess is true. Thanks to Davor Ocelic for reporting it.
	  In the smokeruby_mark() function called during garbage collection,
	  any virtual methods which are called on the instances being checked
	  could have overriden by Ruby methods.  So the Wt::Ruby runtime uses
	  'respond_to()' to find out whether they have been overriden.
	  However, this involves calling 'rb_intern()' on the method name,
	  which means memory could be allocated, giving an error when running under
	  GC.stress mode. So workround it by pre-allocating any strings with
	  rb_intern() for all the C++ methods used in smokeruby_mark()
