the only thing that write and create have in common
is the fact that they both translate to 9p messages.

the beauty of create is that it is atomic.  if you don't
care about atomicity, you can just open if create fails.
using write, the qid could not be returned and there
would always be a race.  since one would not have the
qid, it would be impossible to tell if the race had been
won.
