Why? I suspect if you inverted the control behavior to run the Tcl event loop as it's designed and trigger signals with Tcl_AsyncMark, you would have no problem. Alternatively, you could do Tcl_CreateEventSource, of if threading is really necessary, build Tcl with threads and use Tcl_ThreadQueueEvent. It has all the APIs to approach this from several different angles without have to toss a gratuitous Sleep in there that does nothing more than have people scratch their head and wonder why Tkinter appears so slow.

BTW, I know you were tying into Tk before Tk was properly thread-safe, but those issues have been addressed (although it is highly recommended to stick to using Tk in one thread as things like X aren't guaranteed to be thread-safe).
