[tv] It was just a thought, actually, for instance thinking about tkchat, when a notebook or 'normal' machine is put into hybernation mode (low power (ram is maintained), or sleep mode (all ram swapped to disc)), there is a 'gap' in activeness of the program, which is important for everything with timing in it or connected to the outside world or other programs. When [tkchat] is hybernated, the whole history needs to be reread, which could be a part and done automatically when the machine comes out of hybernation. Detection could be done by a (slow) after chain, which checks for clock ticks continuity.
