, which is called a reentrant lock. The lock object is internally maintained with a lock and a counter object. The Counter object records the number of acquire, so that resources can be require multiple times. Finally, when all Rlock are release, other threads can get the resources. In the same thread, Rlock.acquire can be called multiple times, using this feature to resolve partial deadlock problems .To resolve the deadlock problem:Class _rlock: "" This class implements Reentrant lock objects.
