Although the condensate takes on the average an extensive number of balls, its occupation can oscillate in a wide range. We show that in systems with strong inhomogeneity, the typical melting time of the condensate grows exponentially with the number of balls.10 pages, 5 figuresStatistical MechanicsOther Condensed Mattertext
