Graphs containing subgraphs with differing blocksize

In paper about SC3
http://swiki.hfbk-hamburg.de:8888/MusicTechnology/uploads/321/SC3ICMC2000.pdf
there is a following text:
"Graphs can contain subgraphs. Subgraphs can have differing block
sizes from their parents. Physical models requiring single sample
feedback can be implemented in a Graph with a single sample buffer
size and this Graph can be
embedded in another Graph having a larger buffer size."

What is this actually about, are there any examples of graphs
containing subgraphs with differing block size, and examples of single
sample feedback implemented in a Graph with a single sample buffer
size?

This is about the very first version of SC3. Its quite a different app then
the currrent SC3 architecture.

It did have different block sizes including single sample blocks. I forgot
all about them.

It also had two languages interpreters running. one for the sequencing side
and one for the synthesis side. they communicated to each other by closed
functions: #{ }

there were scaling and efficiency issues and James reworked it into the
current setup where the synth has no interpreter.

and the variable blocks went away too.

there was also a way to write C code directly in your supercollider UGen
classes. you returned a string of C source code and this was compiled to C.
