Details:

When working on a wide field of view image near the disk of the milky way
(which has MANY stars), we noticed that one detection included +600000 clumps
and during its processing, Segment asked for +1Tb of RAM!!!

I had a look into the issue I found that it is caused during the labeling of
the grown clumps into object labels. I am busy fixing the problem.
