See attached patch :). Our library got someone confused in some cases
when the push function couldn't write out, we'd see call traces like

push (X bytes): return Y bytes (Y < X)
push (Z bytes): return -EAGAIN
push (X - Y bytes): abort!

As after an EAGAIN the push function expect to be called again with the
same amount of bytes.
