I don't know off hand of a simple example, but perhaps you'd find
mozilla/netwerk/base/src/nsAsyncStreamListener.cpp a useful example.
Take a look at the implementation of nsIAsyncStreamListener. The
interface is used to proxy nsIStreamListener methods from one thread to
another using event queues.
Essentially, you create a PLEvent object and associate it with a static
callback function. Then you post the event to the desired event queue,
and voila!
You can query a thread's event queue using nsIEventQueueService.
