-          Prevent rbtdb instances being destroyed by multiple threads at the same
-          time. This can trigger assertion failures. [GL #2355]
+          Multiple threads could attempt to destroy a single RBTDB instance at
+          the same time, resulting in an unpredictable but low-probability
+          assertion failure in <filename>free_rbtdb()</filename>. This has been
+          fixed. [GL #2317]
