class Rake::MultiTask
Same as a regular task, but the immediate prerequisites are done in parallel using Ruby threads.

invoke_with_call_chain(task_args, invocation_chain)

Same as invoke, but explicitly pass a call chain to detect circular dependencies. This is largely copied from Rake::Task but has been updated such that if multiple tasks depend on this one in parallel, they will all fail if the first execution of this task fails.
