8.2-RC1 and ZFS

[David Samms]

I gave ZFS a try again this afternoon and immediately came across what I 
would consider a problem.  Simply running dd causes such IO contention 
that a GUI desktop is unusable and MP3s stop playing.  The problem is 
very repeatable, just run dd if=/dev/zero of=big bs=1m count=6400

System is amd64, source updated Dec 27.  Default ZFS parameters. (no 
tuning).  With the same system but UFS+s dd causes no problems.
