There's not really any way for OpenLayers to do anything *other* than
this. Recently (~yesterday) I saw a report on another mailing list
(Boston Perlmonks, for the interested) that IE7 does not re-request from
server in some cases where a 404/error was returned for some unknown
reason. This may mean that the IMAGE_RELOAD_REQUESTS is doing everything
it can, but doesn't actually reload the tile: adding an 'alert' message
in the callback (or turning on debugging and using console.log) might
let yo usee if that's the case, or if IE is just being stupid and not
actually requesting things from the server again.
