In DSF-GDB there _is_ a central place where commands are sent, this is 
where the protocol state is adjusted using -thread-select.  However, the 
--thread option is being added to many but not all commands, so the same 
mechanism that adds the -thread-select could not be reused to add 
--thread option.  Instead each command which accepts --thread that would 
need to be adjusted to use the --thread, but only when in non-stop 
debugging mode.
