/**
 * An interface for events which can dispatch themselves in another thread.
 * This has two uses: first, if your code is in a critical section, calling a
 * synchronized method might deadlock. But by using an ActiveEvent to call
 * the second section, it will not obtain the lock until you have left the
 * critical section, avoiding deadlock. The second use is for calling
 * untrusted code. For example, system code should use an ActiveEvent to
 * invoke user code securely.
