Because fake-time kernels are so last year

I don't think we are prepared to *responsibly* deliver the realtime kernel in FC7. Consider that there have been infinite threads on the trauma Xen has introduced. Such as a zillion patches, often out of sync, etc. Well, currently the realtime kernel is also a zillion patches - many of which conflict with Xen.

afaik, we were not intending to have someone on the realtime space who is constantly keeping up to date with the Fedora rebasing etc (like Juan does for Xen). Sure, Ingo frequently rebases to upstream, but not against the Fedora variants. I just don't want realtime to slow down Fedora. Now, when enough of realtime is in upstream that its a manageable patch set, thats a different story... but that may be FC8.

Things like Xen which are a major integration challenge make much more sense in Fedora. There are installer, system startup, networking, yada, yada to sort out. In contrast, realtime is primarily "just a kernel". So the same integration challenges do not exist (knock on wood). There is already an existing upstream community around the -rt patchset. Based on this, we may not want to fragment the audience.

Mind you, I'm not trying to holdback RT from Fedora. I just don't think its mainstreamed enough to fit responsibly. I welcome opinions though.
