Interesting idea.  For now, we(the front-end) send
 -var-update varxxx
when a new thread is selected. (Can not use -var-update "*", for
some reasone it gets all strange/bizarre if varobj are created for registers too).

Curious, what do you want to accomplish with this, or rather how do
you intend to use it in you emacs port ?
