My yardstick is currently "when a month goes by without anyone

This number is not so large. It seems to be easily crashed by rsync,
for example (speaking from my own experience, and also some of my

I listened to some of Pawel's talks and devsummit brainstormings and I
get the feeling *none* of the problems can be fixed in 7.x, especially
on i386. I'm just asking for more official confirmation.

This is not a trivial question, since it involves deploying systems to
be maintained some years into the future - if ZFS will become stable
relatively shortly, it might be worth putting up with crashes, but if
not, there will be no near-future deployments of it.
