BTW, although this change was not motivated by this I believe this fixes a memory leak. But I'll have to verify first. The effect of the removeContext() call is that all images associated with a user agent will be moved into a WeakHashMap where they can be picked up by the GC. If this isn't done the image cache keeps accumulating Context instances for each processing run.
