I suppose by limiting the jail CPU usage you mean that jails contending over
CPU each get their assigned share. But when the system is idle one jail can
get all the CPU it wants.

I personally prefer the notion of layering the normal scheduler on top
of a simple fair-share scheduler. This would not add any overhead for
the non-jailed case. Complicating the process scheduler poses
maintenance, scalability, and general performance problems.
