As far as I know, 7-current is now in code freeze (though
I haven't seen a "heads up" on this list yes). That means
that it is now becoming progressively stable. Personally
I think that it was quite stable even before it entered

My two cents: It works very well in general. I haven't
seen any reports recently from people who actually lost
any data due to ZFS problems. (Certainly someone will
correct me if I'm wrong.)
However, there are a few things that you should be aware
of. First: The more RAM, the better. Second, ZFS works
much better on amd64 than on i386. That's because of the
larger address space and related vm management. If you
run ZFS on i386, you will need to spend some time on
tuning it (maxvnodes sysctl etc., see the list archives),
otherwise you might run into panics. On amd64, ZFS seems
to run fine out of the box without tuning.
Bottom line: If you intend to set up ZFS with 7-current
on an amd64 machine with a decent amount of RAM -- by all
means, go ahead.
