Interface SignalHandle

public interface SignalHandle
Handle to resolve or reject a named signal on a target invocation. Acquired via InvocationHandle.signal(String).

Unlike awakeables, signals are identified by (invocationId, name) and do not need to be pre-registered: the resolution can arrive before or after the handler starts waiting on the signal.
