wrappers: add some missing lock/wlock grabbing Caught with a hack to turn develwarns into crashes. Unfortunately, I can't check that in because a couple of commitctx() calls in tests turn into deadlocks when I try and fix them.

#!/bin/sh
. $(dirname $0)/common.sh

for b in `hg branches -aq` ; do
    hg co $b || break
    echo verifying $b
    hg svn verify
done
