The SlippyMap extension requires a small change to the original OpenLayers
code. At the very end of the file, it sets a variable to "true", so that the
JavaScript can be loaded asynchronously. The part of the JavaScript that
creates the map polls for these variables. If they are not yet set, the
function calls itself using alarm() and a ~0.5s delay. Without this hack,
the loading of the page would stall at the map in many browsers when using
slow links or slow CPUs
I have to correct myself. The current version of the extension does no
longer include this code. The code was removed in this change:
