Comment (by mlennert):

A colleague who was trying to vectorize +/- 13 mio segments (output of
i.segment) just ran into the same problem of memory saturation during the
topology creation phase.

The tiling approach is interesting, we will look into that, but it would
be nice if a possibility was found to make the whole r.to.vect process
more efficient. I have no idea, how, though...
