# DESCRIPTION:
# refquota, like regular quota, is loosely enforced. A dataset
# can exceed its refquota by one transaction. This loose enforcement
# used to cause problems upon receiving a datastream where its
# refquota is slightly exceeded. This test confirms that we can
# successfully receive a slightly over refquota stream.
#
# STRATEGY:
# 1. Create a filesystem.
# 2. Set a refquota.
# 3. Snapshot the filesystem.
# 4. Send a replication stream to a new filesystem.
# 5. On the original filesystem, fill it up to its quota.
# 6. Snapshot the original filesystem again.
# 7. Send an incremental stream to the same new filesystem.
