TODO.md

• stop serializing options and instead accept webpack config file path and populate fake loader context with that so that worker loaders get access to external options
• pitching loader applier
• pass loader options found on the compiler by the loader name to the loader, like options.transform or options.sassLoader
• accept modified resourcePath from pitching phase and re-read the source
• delay reading the source file until the very point where we need it; pitch
• replay loader RPCs for items cached by loaders like tslint-loader where the output is actually RPCs like this.emitWarning and this.emitError
• better coverage for background loader failures
• caching test
• experiment with not serializing worker output to file and instead shoving things down the process stream (ie compiledPath shizzle)
