From Synchronous to Asynchronous

Profiling our build revealed that our performance problems were caused by looking up files. To fix it, we refactor our code to use an asynchronous file lookup. This is a tricky refactoring, but we take it step by step and everything goes smoothly. By the end of the episode, our file lookup is effectively instant.
