I tried --drive-on-right --check-roundabouts, and the generated map is of
the same size as with r1260.  There are much more diffs than the time
stamps, though.  This is with 3 tiles and 2 cores.

I did not get any warnings or messages on stdout or stderr, or any assertion
failures.  Does this mean that Finland is OK?  Or should I enable some magic
logging property to see the errors?

One more question: What about roundabouts that have been split because of
bus route relations (bus routes would usually not circle the whole
roundabout)?  Does mkgmap merge them already? Could it? Would some
style tagging be needed, in case someone wants to do special line styles
or naming based on bus routes?

Best regards,
