[Tsung] Randomize arrival phase for webserver

[Rodolphe Quiedeville]

Hi,

In the online user's manual it's indicated that it's possible to
randomize the arrival phase :

* Stochastic processes: in order to generate a realistic traffic, user
thinktimes and the arrival rate can be randomize using a probability
distribution (currently exponential)

I can't find how to do this, can you give me some indications ?

Thanks a lot

PS : i'm using tsung 1.3 and 1.2.2
