David you are right. I am trying to think why I thought that. I remember
having a problem with random numbers and I think the problem was due to the
fact that I was calling srand in each thread.
But anyway, you are right. :)

For any process you should seed only once. What I am trying to say is
calleach thread should not seed, only the applications main thread should
constant.srand. All calls to rand will be based on the same seed no matter which
thread they are running in.

I don't think so. The standard rand(), at least, is seeded separately in
each thread.
To the OP: What about just using
n
n + c
n + 2c
n + 3c
where n is derived from the time, and c is some "suitable" integer
