Seems you should use an array of "struct bkend" or "Backend" as storage
in shared memory. I think the problem with Dllist is that it is
dynamically allocated and I don't see how that could be done cleanly in
shared memory. I think that's why the array idea seems best.

Looking up they key would have to be different for fork and fork/exec.
