The Mars Pathfinder had problems due to priority inversion.
Frankly, it seems like a good idea to include support for priority
inversion in the kernel. It's very hard to be SURE that priority inversion can't happen, and in some circumstances if the problem occurs you are in deep trouble. At the least, support for them in user space sounds like a good thing.
