-# Simple locking test case:
-#
-# lock2-1.1: Connect a second process to the database.
-# lock2-1.2: Establish a RESERVED lock with this process.
-# lock2-1.3: Get a SHARED lock with the second process.
-# lock2-1.4: Try for a RESERVED lock with process 2. This fails.
-# lock2-1.5: Try to upgrade the first process to EXCLUSIVE, this fails so
-#            it gets PENDING.
-# lock2-1.6: Release the SHARED lock held by the second process. 
-# lock2-1.7: Attempt to reaquire a SHARED lock with the second process.
-#            this fails due to the PENDING lock.
-# lock2-1.8: Ensure the first process can now upgrade to EXCLUSIVE.
