[SI-LIST] : "Best" way to ground board?

I am designing a 10 layer VME board that has two edge connectors (P1 and
P2). The connectors are about 4" long each with grounds distributed along
the length of each connector.

What is a good way to ground the two GND planes on our board?

A) Simply ground each GND pin to both GND planes at the pin.
B) Something else?

The reason I'm thinking of this is because I can imagine a ground loop
occurring between the outer GND pins of the connectors that are a total of
about 9" away. My guess is that the simple approach will be fine, but I'm
curious as to other opinions.

Any suggestions would be greatly appreciated.

Thanks,

Chris
