It's a good idea, more than a necessity.  If you feel that you have reason to 
believe that the kernel you just compiled actually does work, feel free to 
skip a step and do the installworld at the same time.

However, if you guess was wrong and there is a problem with the new kernel, 
you are stuck with a big problem.  Your new world won't match the old kernel 
image you still have as backup, which tends to make lots of programs like ps, 
ifconfig, firewall software, and the like unhappy and not work right.

So if you do have a problem, don't expect to be able to fix it remotely.
