vertx的线程池设置的maxExecuteTime不生效

问题描述：
1、用createSharedWorkerExecutor(String name, int poolSize, long maxExecuteTime) 获得的WorkerExecutor，设置了100ms的最大执行时间
2、但是在线程执行executeBlocking的worker，超时18分钟后，还会去回调主线程进行处理。

Start with createSharedWorkerExecutor(String name, int poolSize, long maxExecuteTime) and the executeBlocking worker path described in the report. Reproduce the 100ms configuration and compare it with the observed 18-minute delay before the main-thread callback. Done means the configured maximum execution time is respected and the callback behavior matches the intended timeout handling.
