* ext/tcltklib/tcltklib.c: fix SEGV when (thread_)vwait or (thread_)tkwait
* ext/tk/lib/tk.rb: add alias wait_window to wait_destroy
* ext/tk/lib/multi-tk.rb: support calling 'mainloop' on slave interpreters
(however, the 'real' eventloop must be run on the Default Master IP)
* ext/tk/lib/remote-tk.rb: follow the changes of ext/tk/lib/multi-tk.rb
* ext/tk/sample/remote-ip_sample2.rb: ditto
* ext/tk/sample/tkoptdb-safeTk.rb: ditto
