[edit] blocking issue between Rismo's code and ROL locks

Description: The issue with Rismo's code is that he had pushed ROL deletes into a list that were then handled on the main (gui) thread. But you need to do this for both adds and deletes because you can end up with blocking for either one.

The problem then was things in WW and plugins assumed that an add or delete happened immediately so you'd end up with breakage because somethings avoided using the getters and setters but hit the ROL array directly. They would do an ROL.add(...) then try to get at those objects immediately and they weren't there. Or they'd do an ROL.remove(...) and maybe do a dispose on it or something else not nice. So when you got around to handling deletes the object was bad or in some not good state.

The breakage can be pretty obvious (crash) or somewhat more subtle (ROs don't render or behave right).

[edit] Download code error response handling

Description: Download code will download repeatedly request tiles after a error response code from the server, e.g. 400,404. World Wind will also not handle 500 or other server error responses with appropriate time-out behavior.
