Only if you're trying to update them from a different thread.  If
there aren't multiple threads involved, you can update globals from
anywhere.  If that's not working for you there's probably a mistake in
the way you're referring to the variables.  If you post some code we
may be able to help.

A more common approach with perl is to make a handler that runs in an
early phase which reloads the data as needed, and not use a separate
thread.  If you're concerned about reloading the data adding too much
delay to a web request, you could do this in a cleanup handler.
