Thanks, Ben (and Kevin)!
I've effectively applied the portions of this patch that added calls
to svn_error_free(), see revision 1460 for details. This patch was
definitely the inspiration for that.
The rest of the patch is about adding subpools in a few spots, and I
want to sleep on that and discuss w/ Mike, Greg, et al in the morning,
as we generally aim for iteration-based pool control, not depth-based,
except where the benefit is very clear (the svn_wc_entry subpool seems
a strong candidate here, must admit). But anyway, the subpool stuff
seems a conceptually separate change, so didn't commit it with the
pool clear change.
