I haven't seen the rest of this thread, but I presume this is part of
your OOM-avoidance for network I/O framework?

SLOB can be pretty easily expanded to handle a notion of independent
allocation arenas as there are only a couple global variables to switch
between. kfree will also return allocations to the page list (and
therefore arena) from whence they came. That may make it pretty simple
to create and prepopulate reserve pools.
