But if not it does look like you can run into issues.
IIRC
I/O -- A ------ B ------ E ------ G -- I/O | \ / | | \ / | | XX | | / \ | | / \ | I/O -- C ------ D ------ F ------ H -- I/O
Where B is connected to F and D to E. Obviously this setup has a maximum hop count of 3 from any cpu to any other cpu, as opposed to a maximum hop count of 4 for the simple ladder.
