The dashboard's web server answers one request at a time, so converting a big .nif (glom files up to tens of MB) held up every other request, flairs included. - dWeb: Web::Defer hands a request to another thread; the reply is sent from the web thread on its next poll (DeferredQueue). A client that leaves first cancels it and the late reply is dropped. The synchronous route API is unchanged. - Web::Shutdown closes connections while the state their close events touch is still alive; the destructor no longer runs handlers during static destruction (stopping the dashboard aborted in ~WSClient). - WorkerPool: priority lanes, with one thread only for urgent work (flairs, small models, textures), and limited background work. - Scenery: mesh and texture routes (and the showcase's) convert on the pool; thread-safe memory and disk caches, one conversion per model at a time with waiters sharing it; zones are converted ahead onto the disk cache while viewed. - Setting scenery_workers (0: half the cores, 2 to 4).
