That would be a reasonable intermediate step, but I'm worried there
are more assumptions lurking in tere.
In particular is it legal for PI to be in the same iov
entry as data? If not they really need to use a
separate buf entry.
No, in fact that would mean that do/di_pi_nbytes are not an integer
number of iovecs.
