Btw this has already been discussed a few years ago, including the possibility of making an "asynchronous" pd~, which would be definitely useful:

You would typically use it for offloading audio processing to another CPU core, in particular if a single CPU cannot handle the full workload.
So it seems intended for audio rather than control signal operations...
i see how you come to this conclusion by christof's wording.
however, i wouldn't say that this is necessarily true.
Sorry for giving the wrong impression that [pd~] is only for audio processing. Of course, you can (also) do control operations!
the important fact to understand is, that the output of [pd~] is still fully deterministic (by keeping the operations *synchronous* with the parent Pd).
therefore, it is ill-suited for asynchronous offline processing (like training a neural network for 10 minutes at "full speed").
instead i would say that it is a good tool if you can formulate the problem like this: "I have a cool patch X that works great with the desired latency. I have another cool patch Y that also works nicely. But if I use them together, things start to fall apart." then you could run e.g. patch Y in a separate [pd~] instance.
That's actually a pretty good explanation. And that's exactly how I've been using [pd~] myself.
