嵌套管程锁死类似于死锁， 下面是一个嵌套管程锁死的场景：

Thread 1 synchronizes on A
Thread 1 synchronizes on B (while synchronized on A)
Thread 1 decides to wait for a signal from another thread before continuing
Thread 1 calls B.wait() thereby releasing the lock on B, but not A.

Thread 2 needs to lock both A and B (in that sequence)
    to send Thread 1 the signal.
Thread 2 cannot lock A, since Thread 1 still holds the lock on A.
Thread 2 remain blocked indefinately waiting for Thread1
    to release the lock on A

Thread 1 remain blocked indefinately waiting for the signal from
    Thread 2, thereby
    never releasing the lock on A, that must be released to make
    it possible for Thread 2 to send the signal to Thread 1, etc.
