Yes, among other things the new block type should have to be accounted 
for through all the code and documentation. I always try to avoid the 
creation of new block types if possible.

Another way of achieving our goal (to try again slow areas, but leave 
out bad areas) could be to skip ahead when encountering a slow area but 
leaving the skipped area marked as '?', and repeating the first pass 
until all blocks have been tried. After all, slow areas are good areas, 
so this seems a reasonable thing to do.

I'll release in a few days a new version with this implemented.

Antonio.
