1) Is the Pd clock scheduler only accurate to the ms or does it operate at higher than ms accuracy? (As in, if I wanted to role my own mechanism closer to what Seb did, how frequently should my master time go off?)

2) Miller made reference to the linked list of clocks that pd iterates through. Is that something I could access directly? (and if so, where would it live?

3) if anyone knows good books or online resources for learning more about writing scheduler related code, I'm all ears! :-)

thanks
