Paranoia check: can this bug occur with writev() and other
combinations of sizes, or is it only when there is a 0-length
buffer in there?
Only the 0-length buffer at the end of the iovec can trigger this
problem. The PSH bit check during writes is basically:
if (we are emptying the current iovec entry &&
no more iovecs to process)
set PSH bit
Zero length iovec entries do not even make it to this test
since the zero length makes the loop this test is within
never execute.
