Use of signals is frowned upon, in case the authors redefine
them, the appropriate method would be the {r}ndc method in
Cricket's response (which is less typing as well).

Do signals even work on the Microsoft implementations? I assume
they would if you have the tools to send them.

The main alternative to Cricket's suggestion is to use dynamic
DNS, when zone changes (if not adding or removing zones), take
place immediately, but that might be hard work for someone who
is still mastering static zone files.
