[Aoetools-discuss] adding entropy from aoe requests

[Lazy <la...@gm...>]

Hello,

Please take a look at this patch. I have tested it multiple times and
it seems to work.
Is it the right way to gather randomness from aoe ?

I need it because our whole server is running on aoe, and it is short
on entropy.
