Normally, I'd want grounds to have as little resistance as possible, that is, for the ground foils and planes to have the highest possible conductivity.
However, I did once have an exception to this in a GPIB situation where analog signals were being corrupted by GPIB cable currents. I published this in EDN magazine in the January 18, 1990 issue, on page 184, under the title "Resistor Isolates Grounds".
Later today, I'll make a scan of that item and e-mail it to you.
