+dnl Bundle actions with <= 2 ports typically align nicely within ofpbuf memory
+dnl allocation, so will not trigger reallocation codepaths. This test was
+dnl introduced to ensure that when bundle actions with a larger number of ports

+dnl action deep within a list of actions, this test was able to trigger
+dnl Valgrind warnings for use-after-free bugs.
