Yes could be! I'll keep my eyes on the memory.

But in that case wouldn't there be cases where the creation of the first 
threads would be quick and then when a memory limit is reached, the rest 
is slow??
I my case it is either a quick start for all 6 treads or all of them 
takes 30 seconds each.

Thanks for your help
