Query: Barabasi Queueing Model and Invasion Percolation on a tree   In this paper we study the properties of the Barab\'asi model of queueing
under the hypothesis that the number of tasks is steadily growing in time. We
map this model exactly onto an Invasion Percolation dynamics on a Cayley tree.
This allows to recover the correct waiting time distribution $P_W(\tau)\sim
\tau^{-3/2}$ at the stationary state (as observed in different realistic data)
and also to characterize it as a sequence of causally and geometrically
connected bursts of activity. We also find that the approach to stationarity is
very slow.
