// time, so external resources should be locked if there are multiple clients. Adding handlers is not thread
// safe and should be done prior to clients being created.Handle. Also, this handler will block the individual
// client's event loop, so long operations that include network requests and the like should be done in a
// goroutine with the needed data **copied** from the handler function.
