So every unrelated request that happened to be currently processed is thrown away because of a rare corner case, and with no way to intercept shutdown and save state, flush buffers, or anything. Yes, totally right granulation.

Not to mention that you have just introduced a very complicated piece of software to run a single daemon.

Or, you just catch the panic in a defer up the call chain, log the error, and then exit that goroutine. Like: https://golang.org/src/net/http/server.go#L1694
