ruby--ruby/ext/tk/tcltklib.c
nagai d2271cbdd1 * ext/tk/tcltklib.c: make SEGV risk lower at exit. 
* ext/tk/lib/tk.rb: ditto.

* ext/tk/lib/multi-tk.rb: fail to call function-style methods on slave
  interpreters. The strategy (MultiTkIp_PseudoToplevel_Evaluable) to
  fix the problem is a little tricky. You may have to take care of
  conflicting with it.
* ext/tk/lib/tk.rb: a little change for the pseudo-toplevel strategy.
* ext/tk/lib/tk/font.rb: ditto.
* ext/tk/lib/tk/msgcat.rb: ditto.
* ext/tk/lib/tkextlib/itk/incr_tk.rb: ditto.

* ext/tk/sample/demos-en/widget: fail to call function-style methods
  on sample scripts. To fix it, a strategy which similar to the way
  on MultiTiIp is used. Please take care when re-write and re-run a
  demo script on the Widget-Demo code viewer.
* ext/tk/sample/demos-jp/widget: ditto.
