Another important property of Ingo's scheduler is that the time is measured in nanoseconds. According to a later email, Ingo said that the earlier version without the high precision and using queues didn't work well at all. This are the two things that seem to have been limiting RSDL and other schedulers, as strange artefacts cropped up because of the queue and low granularity design.
Peter William (of plugsched) also wrote a scheduler, and experience with trying out different things.
William Lee Irwin III (now I understand why people call him wli ;-) is hammering on the importance of a standard test suite for schedulers, so if there are people with free time who want to help him with setting one up...

there isn't really a standard testsuite, but many of the problem cases (and the little code snippets to show 'em) are sticking around, and are used for testing new scheduler improvements/changes. Quite a few float around on the LKML and also on Dr Con's mailinglist.
