[PD] audio send recieve feedback quirk

I found this behaviour slightly surprising, but on reflection it makes sense. 
Pd doesn't seem to check deeply into subpatches when looking for DSP feedback
loops. 

I started making a simple waveguide synth and decided, for a change, to work on
the feedback mechanism inside another subpatch. I kept getting DSP loop error
even though the signal path contains a [s~] and unique matching [r~]. Making
the feedback loop require a [send~] and [receive~] in the outermost block seems
to defeat the use of smaller blocksizes in subpatches. 

Anyone care to comment on this (attached example). Or am I understanding this
incorrectly?

Cheers.
Andy
