There could be problems. If that happens, I can program a loop to solve
it. So far, nobody reported such problems. Perhaps nobody has huge
collections of zoom 17 tiles - or maybe python has no problem invoking
curl with a 7MB parameter list.
Fixing this in advance is a better approach - but I'd rather spend time
on a much better fix using libcurl. That would speed yaouh up further
also. But this have to wait until someone ports pycurl to the freerunner.
