I didn't make myself clear. In order for HotSpot to have dramatic performance improvements, we need kernel threads. HotSpot assumes that multiple system calls can be made at the same time, and as such *requires* kernel threads. (At least, this is the consensus we came up with while talking with the Sun engineers.)
