tdb ACLs are a good idea for production use.   I really should make
this more clear. 

The TDB approach creates a dev/inode indexed DB, rather than using the
file system.  This is prone to inode re-use issues, and while we have
defences for the ACL side of that (we hash the POSIX ACL on the file),
there is no such defence for other extended attributes that might also
be stored there.
