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.
