What I'm confused about is:
Instance of JSContext was created in the work queue, and there was no code that access JSCore in the main thread,but JSC::JSRunLoopTimer::Manager::timerDidFire executed in the main thread.
Sometimes,I got a dead-lock.
The call stack of the main thread:

What do you mean by “work queue” in this context?
