this comment will need updating if we do add this error in here (but see other
comments)

Our case belongs to 'c', isn't it?

fair enough. (c) was sufficiently general it didn't mean much to me so my eyes
skimmed past it.

Also, conceivably, the webview user can catch and ignore this error, so in that
respect it's an init failure not a process "termination" but yes this is locally
consistent with the terminology we use in chromium content AndroidProcess  etc
so lets go with it like this.
