I would need something like flush_threadlet_queue for the vnc server. I need it in vnc_disconnect(), vnc_dpy_resize() and vnc_dpy_cpy() so wait (and/or abort) current encoding jobs.
I'm not sure threadlets are the right thing for the VNC server. The VNC server wants one dedicated thread. Threadlets are a thread pool. You could potentially use one thread per client but I doubt it would be worth it.
At any rate, flushing the full queue is overkill. You want to wait for your specific thread to terminate and you want to block execution until that happens. IOW, you want to join the thread.
