It would be useful for commands that do not access the running
inferior.  Simple examples include `help' commands.  Less trivial
examples include commands that consult the symbol tables.  Really
tricky commands would be useful if and when GDB supports debugging
more than one program--you could examine data in one program while the
other one runs.

But, as Daniel points out, for now this is just an infrastructure that
still awaits to be used.
