Although reading in the hpd spec: "By defining actionpoints, the user may request in advance that target program execution stop under certain conditions". Do we want the display to be similar to a watchpoint, except it applies to an expression rather than a single variable? Or do we want it to be an expression that is displayed when the program stops (I remember Andrew saying something about how gdb does this, and it's bad, so we probably want to avoid that). While what the DisplayValue object is capable is well defined, I guess I'm not 100% sure of how it will be used.
