Serial queues (also kNown as private dispatch queues) execute one task
at a time in the order in which they are added to the queue. The
currently executing task runs on a distinct thread (which can vary
from task to task) that is managed by the dispatch queue.

具体来说,对于主队列,是：

The main dispatch queue is a globally available serial queue that executes tasks on the application’s main thread. […] Because it runs on your application’s main thread,the main queue is often used as a key synchronization point for an application.
