what is the reason that p9p doesn't support procrfork?
linux might be able to support procrfork via clone(2), but
of course, pthreads might have something else to say about
that.

you answered the question yourself.
we're not programming to linux.
we're programming to what we can do
portably across a range of unixes.
file descriptor and name space groups
(the only things you ever use procrfork for)
are not part of that.
if you need procrfork for rffdg before procexec, usually
you can get by with threadexec etc.

all the worlds a vax, i mean, a linux box. ;-)
i misread the source. i was reading Linux.c;
i didn't realize that that is only for nptl.
actually, i was thinking about ndb/dns is doing.
