i have one concern about this that i talked to takashi about when we were in bordeaux. it seems to me that the ALSA xrun debug stuff is measuring things when the interrupt handler for the ALSA device executes and detects an xrun. if the handler itself was delayed, then the stack trace for its execution doesn't or might not show what caused the delay. this means, perhaps, that we need to be rather careful interpreting these traces.
