Thanks to you both. I ended up doing this on the server:
```svnadmin lslocks /usr/local/repositories/reponame/ | grep -B3 "Owner: alice" | grep "Path: " | sed 's/^Path: \//svn unlock --force "/' | sed 's/$/"/' > ~/svnunlock.sh
```then running that result on my own computer against my local working copy.
