What kind of for loop?  I'm trying to reproduce the problem, but the above code works fine.  You have to be clearer about what exactly you are doing.  Please come up with a simple piece of code that exhibits the problem, not some pseudo code that leaves out the details.  Obviously, if you run the above 1000 times, you allocate 200000 variables and that takes a lot of memory, but that's not what you said in the original message.  
Calling dom (as opposed to constraining the domains directly) is definitely not the problem here, it does not allocate any memory except for the domain itself.

Cheers,
	Guido
