The wc.db and work_queue are part of WC-NG (with centralized
metadata), which was introduced with 1.7. The previous working copy
design was very different (small metadata files scattered around in
the .svn directories in each subdirectory of the working copy).

It's possible that 1.6 could exit more cleanly in this situation,
without leaving locks, I'm not sure (and I don't have a 1.6 laying
around here right now). Maybe you or someone else on this list can
verify this.

But certainly all 1.7.x versions should have the same problem as what
you're seeing now (at least I don't know of any change in the 1.7.x
line that could have changed this).
