Well, an idle function runs continuously whenever Gtk is doing nothing, so
obviously it will use 100% CPU. :-)

I can't think of anything intelligent to say without knowing more about
Tcl. But clearly an idle function isn't what you want. You need to figure
out a way to know when there are Tcl events (when you run a command? when
there's activity on a certain file descriptor?). Then you run the Tcl loop
when you get the Tcl events.
