I keep hearing rumors that the kernel devs are basically trying to make 
the vanilla kernel "rt-capable", meaning I think that they want to make 
special patching unnecessary for the task. What we're seeing now are 
side-effects of this effort, which will hopefully right itself soon.

Only rumors, I'm afraid. If someone out there has some real knowledge on 
this issue, feel free to speak up. :-)
