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
Is this a bug the OpenLayers developers know about and might be fixed in a future version of OpenLayers itself?
This is no OpenLayers specific issue, it's just how most web browsers work, and a well known workaround for it.
