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.
