Unfortunately this is cripplingly slow:

$ time symlinks -r . | egrep '^dangling: .+/\.git/annex/objects/' |
awk '{print $2}' >/dev/null
symlinks -r .  0.15s user 0.37s system 97% cpu 0.536 total
egrep '^dangling: .+/\.git/annex/objects/'  0.01s user 0.00s system 1%
cpu 0.534 total
awk '{print $2}' > /dev/null  0.00s user 0.00s system 1% cpu 0.526 total

$ time git annex find --not --in= >/dev/null
git annex find --not --in= > /dev/null  6.73s user 1.76s system 21%
cpu 39.483 total

Ouch!  Joey, is there an optimization that can be made for the local case here?
