Let's say you make a walkcycle, and use the Stride Bone feature to 
make your character walk along a path. That's nice, but it's very 
reptitive. Let's say you want to move the foot position on three out 
of forty footfalls to step on something exactly? Or, that you want to 
alter each step a bit so it looks more natural? You can't do that 
with a walkcycle. But, if you bake it into a single action, with each 
loop of the cycle as real IPOs in an action, you can tweak and 
sweeten each step, if you like. Also, it should cut down on the work 
that Blender has to do, as it's simply evaluation a linear chain of 
Ipos, and not having to run mutliple cycles of NLA evaluation. It may 
not be a big deal for a single character scene, but if you have a lot 
of folks jumping around, it could make a serious difference in system

You can read the docs and demos from the Patch Tracker on it:

Although the patch in that particular tracker item is superceded by 
the one bundled with Action Baking.
