The Dink Network

Wait,
I just tested and at least on YeOldeDink, wait(0) seems to always wait at least 2 frames.

Or more specificially, I made a script that runs this code:

	loop:
	&seq = sp_seq(&current_sprite, -1);
	&frame = sp_frame(&current_sprite, -1);
	&pseq = sp_pseq(&current_sprite, -1);
	&pframe = sp_pframe(&current_sprite, -1);
	debug("seq &seq frame &frame pseq &pseq pframe &pframe");
	wait(1);
	goto loop;

and there were two calls to update_frame between each time the loop was run.

Is this YOD issue or does this also happen on vanilla Dink and HD?
