I haven't looked at it in the debugger. The code that uses PingLoader
might well call dispatchWillSendRequest on the ResourceRequest.
There are classes called MumbleLoader that inhabit every layer of the
loader. For example, PingLoader is a very low-level object. It's a
peer to SubresourceLoader, not to DocumentLoader, FrameLoader, or
CachedResourceLoader. One easy win would be to rename these classes
so that the different layers had different names...
