unit Futures;

interface

// A "future" is an object that promises to provide a value
// sometime in the future. The value is computed in a background
// thread. When the application needs the value, it requests the
// value from the future--if the future isn't done, the application
// waits until the value is ready.
//
// All the synchronization issues are hidden from the application.
//
// Use the TFuture class by deriving a new class that overrides
// the Compute method.
