Indeed, it deserves documentation and broader use.  Even on its first
day in master I found it game-changing for testing large Samba
domains. 

Like Tim mentions, instead of fussing about with a VM and networks, I
could restore a pre-built large domain right into the testenv where I
do most of my work.

That means more time testing and less time speculating :-)

Because it detects the domain and realm, it can even take a backup from
production, but because the testenv is isolated by socket_wrapper, it
won't conflict.
