this kernel, so I assumed realtime FreeBSD would be ramping up. Sadly,
not a lot of activity in the realtime yet.

A positive attitude may not solve all your problems, but it will annoy
enough people to make it worth the effort.
If there are no stupid questions, then what kind of questions do stupid
people ask? Do they get smart just in time to ask questions?
