Temporary

The temporary collection keeps track of the global collection of temporary cleanup tasks in instances where temporary-generating tasks are executed directly via their run() method, rather than as part of a collection.

In general, temporary-generating tasks should always be run in a collection, as the cleanup functions registered with the Temporary collection will not run until requested.

Since the results could be undefined if cleanup functions were called at arbitrary times during a program's execution, cleanup should only be done immeidately prior to program termination, when there is no danger of cleaning up after some unrelated task.

An application need never use Temporary directly, save to call Temporary::wrap() inside Tasks or Shortcuts, and to call Temporary::complete() immediately prior to terminating. This is recommended, but not required; this function will be registered as a shutdown function, and called on termination.
