Wow! My network daemon at work, written in Lua (which uses Lua coroutines for processing, which are similar enough to Go routines/channels for this comparison) has a supervision tree. It can log the unexpected death of Lua coroutines and keep going, which is nice for the unexpected bit of input [1]. It's also helpful when testing new code as unexpected errors are logged (stack dump, so the location of the crash is reported) in development/QA.

[1] Yeah yeah, all input should be well specified. Could you please inform the vendors that their programs are spewing unspecified crap at me? Thanks.

Go can do almost the exact same thing, in fact, it's baked into the stock http server library.
