Goroutine panic wrapper. The objective is to be able to launch goroutines and tell if any of them have panicked. The primary use for this is in a testing framework where we want testcases to abort when an assertion fails and we sometimes want to use goroutines in tests.

func main() {
defer func() {
if e := recover(); e != nil {
fmt.Printf("Recovered from '%v'\n", e)

Objectives:
1. Avoid file system implementation bias on libcontainer API
2. Make the caller of the API responsible for storing/persisting the state necessary to re-create
a container from the underlying cgroups, etc.
3. Ideally, clarify the notion of ownership in the API to avoid write conflicts due to misunderstanding.
At a minimum this needs to be clearly documented.
Current situation
Caller passes a file system path on Create. libcontainer stores a "memento" (file) there sufficient to
