hi 
I encountered some similar problems when trying to read from a socket
while running at Tk app.
The main problem, I suppose, is that threads are implemented in the ruby
interpreter while Tk.mainloop
is running in the binary library tcltk.

the solution I found is to run Tk.mainloop, and then call the reads from
inside the Tk.mainloop using Tk.After:


  inp=Thread.new(){

            timer=TkAfter.new(100,-1,proc {$igsClient.getlines})
        timer.start
     }
  



(100ms, -1 == loop)
