Isn't tuning trace _lengths_ more important on pcbs than what types
of corners you're using?
On my AMD motherboard, the bus traces have s-shaped wiggles in them to
keep the lengths all the same. Rounded corners, too.
I have several boards from a Cray-1 supercomputer here; they are
chock full of such wiggles. The processor modules in the Cray J90
machines also have those wiggles. If I can find the motivation (or the
caffeine) I may take a few pics of them.
