No. Breadth-first (queueing) is the execution model of t_clock components, 
which are central to [delay], [pipe], [metro], and other such things.

I say that breadth-first is queueing, because if you replace every 
connection by a generic message pipe that does the same to messages as 
[pipe 0] does to floats, then a tree (of objects and connections) gets 
traversed breadth-first, as anything down gets delayed to after the 
current stack of things is done with, in the t_clock queue of things to do 
«now».

However, the DSP uses a model in which data is flowing more regularly, 
such that order of execution often does not matter, as for example, if I 
take data from [osc~] into both an [expr~] and a [cpole~], and from both 
of them into a [*~], then the [*~] will get the same data regardless of 
whether [expr~] or [cpole~] gets executed first. The only place where this 
breaks, is if a given DSP order causes a 1-block delay on certain 
send/receive or throw/catch tasks. And also dsp loops are forbidden.
