+- Build the path cache asynchronously without blocking the main thread -> Big projects no longer freeze Atom
+- Build the cache in parallel (fast-glob uses threads underneath)
+- Unified method for building the cache on all platforms
+- Allows using glob for pattern ignoring which is the most common way of writing path patterns
