Ok, I think there actually 2 ways to resolve this:
1. Add early exits if m_reachedTerminalState if true in didFail() and didFinishLoading().
2. As you've suggested previously, change SubresourceLoader::releaseResources() to only clear variables, not heavy lifting like calling CachedResourceLoader::loadDone().

#2 is more extensive and would probably still allow cases like this to call releaseResources() twice (and therefore trigger assertions in debug), but would make calling releaseResources() multiple times benign.
