465Allocate $time seconds of blocking CPU time at priority C<$priority>:
466This call blocks and returns only when you have at least C<$time> seconds
467of cpu time till the next tick. The slot is only valid till the next cede.
468
469The optional C<$name> can be used to identify the job to run. It might be
470used for statistical purposes and should identify the same time-class.
