/* Notes:
* We hope to create a complete set of thread-safe entry points someday,
* which will mean a set of getXbyY() functions that take as an argument
* a pointer to the map class, which will have a pointer to the private
* data, which will be used preferentially to the static variables that
* are necessary to support the "classic" interface. This "classic"
* interface will then be reimplemented as stubs on top of the thread
* safe modules, and will keep the map class pointers as their only
* static data. HOWEVER, we are not there yet. So while we will call
* the just-barely-converted map class methods with map class pointers,
* right now they probably all still use statics. We're not fooling
* anybody, and we're not trying to (yet).
