SourceMap files and resources downloaded by the frontend are currently downloaded synchronously. That is poor and in some cases I've even seen a 10s timeout resulting in a 10s hang in the UI.

Most of the time when the frontend wants to download a resource it will want to download the resource through the backend. And even have caching behavior. For instance if you're remotely debugging an application that loads web content from its hard disk (file:///) attempting to load the SourceMap resources from the host machine (frontend) won't work. and worst case could produce unexpected results.
