174This array contains the results of the last C<invoke ()> call. When
175C<cf::override> is called C<@cf::INVOKE_RESULTS> is set to the parameters of

330This call blocks and returns only when you have at least C<$time> seconds
331of cpu time till the next tick. The slot is only valid till the next cede.
332
333The optional C<$name> can be used to identify the job to run. It might be
334used for statistical purposes and should identify the same time-class.

336Useful for short background jobs.
