kernel - Add usched_dfly algorith, set as default for now (6)
* Fix an edge case where the pairing could cause flapping.
* Fix an edge case where user processes were interrupting each other
when they were in the same queue, which could cause a synchronous
process like a postgres server to lose cpu while holding internal
locks during a short operation.
