No way.  We need to reduce the numer of iovec traversals, not adding
more of them.

ok, I can work on a version of this that uses struct iodesc.  Maybe
something like this?

struct iodesc {
       struct iovec *iov;
       unsigned long nr_segs;
       size_t nbytes;
};

I suppose it's worth doing the iodesc thing along with this patchset
anyway, since it'll avoid an extra round of interface churn.
