同一个线程多次获取资源，NodeSelectorSlot类中的DefaultNode的curThreadNum会不断增加，是不是有问题？


Start by reading the NodeSelectorSlot and DefaultNode classes, then inspect the attached reproduction image and the issue's existing comment. Determine whether repeated resource acquisition by the same thread is expected to change DefaultNode.curThreadNum. Done means the counter behavior is explained with a reproducible expected-versus-actual result and a confirmed resolution path.
