Determining completion is indeed tricky, especially where remote hosts
are involved. But there are already two good choices for the interface:
write() blocks until the buffer may be reused by the application,
aio_write() instead posts a notification. What does vmsplice() add?

(Changing to a vector operation changes the names of the functions, but
not the nature of the question).

Blocking on the next vmsplice comes automatically, since you can't replace buffers that haven't been ->release'd yet. So that's how it already works. As I said, the missing bit is getting the release right.
