Assuming you mean "delete the slave zone *file*", this doesn't actually
work (unless you restart BIND as well). Tested with 9.8.2rc2, but it
seemed innately unlikely. Why would BIND on the slave ever look at the
file contents except on startup?

Or did you mean something like (1) remove the zone from the slave's
configuration and "rndc reconfig" (reload is overkill) (2) delete the
slave zone file (3) add the zone to the slave's configuration again
and "rndc reconfig" ?

That would work, but "rndc retransfer [zone]" is a lot simpler!
