Initial load takes ~10 seconds

Not sure if this is related to the issue concerning disk access occurring on the main thread, or if I'm doing something wrong (though the image loader interface is so simple it's hard to figure out what).

I have a grid adapter that uses a cursor over the media gallery. Pass in images & views to imageloader.loadImage() as standard. The time between the loadImage method being called and an image displaying in the relevant view is ~10 seconds. If I pass a listener in to the method, sure enough it doesn't get called until 10 seconds after the loadImage() call. This only happens for an image loaded from disk - when loaded from memory, performance is as would be expected.

I can provide code if needed.

More on this: the issue does not appear every time; sometimes photos will load near-instantly, even when loaded from disk. The problem seems to occur deep within the guts of AsyncImageRequest, between the creation of a new AsyncImageRequest and its execution, in ImageCacher:

        new AsyncImageRequest(cacheRequest, imageCacherListener).execute();

The doInBackground() operation may occur as much as 45 seconds after the object is created. I'm not sure if this is due to excessive amounts of AsyncTasks in the queue, and if so whether this can be controlled in some way, but hopefully this helps.
