In summary I hope this article offers some solid advice around dealing with Go’s mutexes. Please play with Go’s lower-level synchronization primitives, make your mistakes, respect and understand the tools. Above all, be pragmatic in your development and use the right tool for the job. Don’t be scared like I was originally. If I always listened to every negative thing said about multi-threaded programming and locking I wouldn’t be in this business today writing kick-ass distributed systems while getting to use a kick-ass language like Go.
