Yielding to the UGen graph is exactly the same as yielding to the
other shreds. The UGens are in lock-step with the shreds for the
purposes of strong timing.
Yes, you are right, of course.
Stephen said it much better then I did. Either that or we are after something that's fundamentally impossible.
Let me try again; I want a computationally intensive shred to Shredule itself for the moment when the VM "now" again equals how long ChucK has been running. I think that's exactly what Stephen proposed but we could easily be barking up entirely different trees. It's a tricky problem and very tricky to talk about, I now realise (pun intended).
