多线程之常见问题

死锁产生条件

1. Mutual Exclusion: Only one process can access a resource at a given time. Or, more accurately, there is limited access to a resource. A deadlock could also occur if a resource has limited quantity.
2. Hold and wait: Processes already holding a resource can request additional resources, without relinquishing their current resources
3. No preemption: One process cannot forcibly remove another process' resource
4. Circular wait: Two or more processes form a circular chain where each process is waiting on another resource in the chain
