"sched_yield" means "give up the cpu to lower priority processes", because, frankly, if there were higher priority ones.. they'd already be running.

What maybe would be useful is a yield_to() which takes a pid. However that currently doesn't exist. -- fedora-devel-list mailing list fedora-devel-list@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/fedora-devel-list
