What does m_networkLoad->description() return? Hopefully it doesn't contain anything sensitive like URL?

Also, why can't we move this LOG line *before* calling start()?

This patch isn't about verifying the string returns the right thing.

Putting the log line before start() makes it categorically false, as start() may not actually *start*

And yet still a good thing to verify and you didn't answer.

I feel like a safer fix would have been to update the actual code that introduced the regression and have NetworkLoad::start() call didCompleteWithError: asynchronously when it fails due to FTP. There are other clients to NetworkLoad than NetworkResourceLoader and having start() call that may fail synchronously and delete |this| might be an issue for other call sites as well.

0x105d74000 - [pageProxyID=21, webPageID=22, frameID=3, resourceID=32, isMainResource=1, destination=3, isSynchronous=0] NetworkResourceLoader::startNetworkLoad: Going to the network (description=LocalDataTask <25187A1B-3324-4E2C-982A-AB468520286C>.<1>)

Now I have my answer.
