That's what I had first, and I was still seeing crashes, so I added removal of
the methods keyed on their signature.  This then removed all crashes.

It seems to me that if some unrelated methods are removed, that shouldn't be a
big deal as they'll just be added to the cache again on their next use, and it
shouldn't be a big performance hit as methods are removed only when an image is
deleted, which is presumably a relatively rare event ...
