it doesn't matter as long as every writer opens the file independently.
(the server then buffers on a per-fid basis).

BTW, the "perform action on clunk" choice has another potential
problem (besides lack of diagnostic feedback) - it forces the
file to be opened once for each control request, which implies
at least 3 more 9p requests each time. probably not an issue, but
might become one if doing many such requests over a network.
