I'd be tempted to run a -current jail inside of an 8.x base system.  
That's not supported, but would likely work.

An even better idea might be to run a -current system inside a 
VirtualBox container.  This would allow you to run it at full speed, but 
insulate your primary system if there's bad things going on with 
-current this week.  I do a lot of FreeBSD development inside of 
VirtualBox.  It is quite nice that way.
