Generally, you can't assign a callback to be executed
in any other thread then your current thread. You can
however send a script to be run in some other thread
either synchronously or asynchronously by using the
thread::send command of the Tcl threading extension
(a part of the Tcl project on SF).

If you want to do all this from the C-level, then
you might want to get yourself acquainted with
Tcl event loop processing and most specifically the
Tcl_ThreadAlert API call.

I do not know if this helps...
