Same pattern as the async variant; runs on the completing thread.
<cfscript>
future = runAsync(function() { return 10; }).thenApplyAsync(function(x) { return x * 2; }) .whenComplete(function(value, error) {
variables.completed = true;
variables.finalValue = value; });
future.get();writeOutput(variables.completed & ":" & variables.finalValue); // true:20
