[Devel] rand function in config file

[Henning Westerholt]

Hello all,

i need a function that return true or false, depending on a probability that 
can be changed on runtime, e.g. with a fifo command.

The purpose of this function is simple load shedding, if for example to many 
clients register on a given time, then i could send a error message to e.g. 
40% of them.

Should i build a simple module for this function, or is this is a change that 
is more reasonable implemented in the core? 

I just want to ask, perhaps there is interest to later include this function 
in the trunk.

Cheers,

Henning
