I'm sorry but I cannot show you any good solution for your problem. 
If you want to control running status of Tk.mainloop, 
you must use one thread for Tk.mainloop. 
A simple example is 
--------------------------------
th = TkThread.new{Tk.mainloop}
 :
 :
th.kill
th = TkThread.new{Tk.mainloop}
--------------------------------
Another one is
--------------------------------
class TkEventLoopSleep < StandardError; end
th = Thread.new{
  begin
    Tk.mainloop
  rescue TkEventLoopSleep
    sleep
    retry
  end
}
 :
 :
th.raise(TkEventLoopSleep)
 :
 :
th.run
--------------------------------
But attention!.
Sometimes, they generate other problem that is slowdown of Tk response.
