I'd create an instance of asynchronous application that handles all long running
events.

The async app needs to keep multiple queues for different
users and when an ordinary (sync) application handles the rest.

Now when new message arrives you just need to notify an async. app on such
a message and push it to an appropriate queue. Note if you push a message
from sync. app. to async. one you need to pass it via service().post()
to the thread that runs the event loop.

   

   std::string new_message=...,user=...;   service().post([=]{ 
      // will be executed in event loop's thread

      global_async_app_ptr->handle_new_message_for_user(new_message,user);

   });
