   • 2000, Douglas Lea, Concurrent Programming in Java, Addison-Wesley Professional, →ISBN, page 88:

     If synchronization is always performed in least-first order with respect to object tags, then situations can never arise in which one thread has the synchronization lock for x while waiting for y and another has the lock for y while waiting for x. Instead, they will both obtain the locks in the same order, thus avoiding this form of deadlock.

1. (intransitive) To cause or come to a deadlock.
   • 2004, Scott Oaks; Henry Wong, Java Threads, O'Reilly Media, →ISBN, page 123:

     Since we cannot solve this problem completely, it may sometimes be better to use explicit locks and risk deadlock if a thread exits unexpectedly. It may be better to have a deadlocked system than to have a corrupted system.
