Perhaps this could eventually be modified to draw from a prezeroed block of memory, similar to the current code for doing the same thing for userspace. It probably wouldn't give much performance gain, especially since it's not used for large blocks or large numbers of small objects (As you would use a slabcache for those), but it might help a bit. Of course, the code would need to fall back quickly if such an allocation would be messy or expensive for any reason.
