Discussion

This module contains the routines for raising background exceptions, and those for registering callback commands in each interp to handle them. Except for the connection to interp bgerror and an edge case of hidden command invocation, these routines can be created entirely outside the Tcl public interface as well. Moving this submodule into interp should be considered.
