Is there any attempt to debug the RSS feed?  Do we know how often 
it misses edits?

Great to hear that.  I hope I can help.

OK, so maybe set it at 3 hours.  But is there any timeout at all 
today?  I think many people can install tilesGen.pl and try it 
out, without ever requesting a password for uploading.  It is a 
pity if this blocks anybody else from rendering the same tile.

Ever since I got involved in OSM, tile rendering has been a great 
problem.  Now with Tiles at home we have a method where more people 
can help, and this is great.  I think we need to look at the whole 
chain of events from editing the map, to seeing the new tiles: How 
often does the chain fail (e.g. RSS misses the edit) and when it 
does succeed, how long does it take?  If we can measure these 
parameters, we can start to make improvements.
