Method WaitAll

server/parent.go:108–126

WaitAll returns a channel that is closed when all children have exited. Caller should call this after SignalAll to wait for graceful shutdown. NOTE: This method creates a new goroutine each time it's called. It captures a snapshot of current children at call time - children added after the call won

// a snapshot of current children at call time - children added after the call
// won't be waited on. For typical shutdown scenarios, call this once after SignalAll.
