+Check potential race condition around transaction and working copy data
+=======================================================================
+
+#testcases bookmarks-in-store bookmarks-wc-level
+
+The transaction is garanteed to run with the lock, but may runs without the
+wlock. So if the transaction backup/restore some content related to the
+working-copy and protected by the wlock, we might run into trouble if another
+process grab the wlock and modify them.
+
+This test file is testing various cases where such parallel changes happens to
+validate the transaction behavior.
+
+Other is used to get a simple pull source. As pull is a simple way to create
+transaction without the wlock.
+
+Setup

+Avoid long deadlock
