I can give it a shot.

I think perhaps a bigger reason why this might be only just turning up,
is that I now have an upper bound on the number of entries in an iovec
at 256 entries.  So now there's more chance that we'll generate an iovec
that a syscall can actually use instead of us running out of memory
trying to satisfy every entry and constructing a broken iovec struct if
we hit ENOMEM
