That's not strictly true - if A and B simultaneously respond to X,
then C and D could simultaneously respond to B (not having seen A),
and now we have nesting.
You could argue this will be infrequent, and threads will mostly be
linear with only the occasional simultaneous send (and with nesting
If that's true, maybe the UI doesn't need to display nested
structures, but just needs to show some sign for "muddle" or
"simultaneous send" when things get more complex than linear?
