Could you be specific by what you mean by "quota"?  Just to be clear
about it all...  I use a number of filesystems that have the quota
attribute (zfs get quota / zfs set quota=something <foo>) set and do not
observe this.  However, there are user quotas too and I don't use them.
I also am using ZFS with 9.x mostly and not -current.  The latest build
I have is 9.99.74 and also does not appear to have this problem.
