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.
