Knowing if an XserverRegion is empty

Sorry if this is a stupid question, but is it possible to know when an
XserverRegion is empty? My use case is I iterate over a list or
XserverRegions subtracting them from a larger region. I'd like to be
able to stop iterating the list once the larger region has had
everything subtracted from it. Is this possible?
