Also there are certain conditions that can worsen the thrashing. Threads really only addresses periodic brief pauses (assuming your cpu is PII or better). The long pauses can be exasperated by a couple things having to do with tile caching. One is excessive visibility, if you hit the z key to expand your visibility to unusually long distances the number of tiles in the scenery cache grows exponentially. Another factor can have to do with the location of "views" and switching views. The tower views (views 3 and 4) are setup at your starting location. If you fly far away, so that the scenery tiles local to the aircraft are completely different than those at the tower it is possible to trigger thrashing by switching back to that tower view. This doesn't seem to be much of an issue on my system, but if combined with an expanded visibility, it can easily thrash itself to a crash. If we had a gps style "get nearest airport" it might be fun to have the towers follow along, which would help that issue. There is a bug in there however, that produces crashes under certain circumstances. I've never been able to pinpoint just what it is. It does seem to be associated with thrashing (and initiated by/with excessive thrashing). Obviously, with any amount of thrashing the scenery code should be able to recover eventually.
