It is, which is part of why we were trying to kill it. The primary users
were thing growing buffers ala realloc. So we were pushing to change the
callers to just do a realloc. But IPSEC doesn't fit well into that mold.

The fundamental problem here for networking is that 1500 is not very
close to a power of two and just about everything in the VM wants it to
be. If we could get SKBs fitting more nicely in memory, I think it would
cease to be a concern.
