505Allocate $time seconds of blocking CPU time at priority C<$priority>
506(default: 0): This call blocks and returns only when you have at least
507C<$time> seconds of cpu time till the next tick. The slot is only valid
508till the next cede.
509
510Background jobs should use a priority les than zero, interactive jobs
511should use 100 or more.
512
513The optional C<$name> can be used to identify the job to run. It might be
514used for statistical purposes and should identify the same time-class.
515
516Useful for short background jobs.
