    "Hi, Amigo!" "I want to tell you about a couple strategies for avoiding deadlocks." "The best strategy is a thoughtful architecture and a set of rules governing when and in what order you can use locks (acquire mutexes). The classic approach to the problem is to develop a lock hierarchy and establish the rule that certain locks can never be acquired in a state where certain other locks have already been acquired ...."
