Generally speaking, one does not care about the memory usage of Ant unless 
you're working with a task that gets repeated a LOT.

Just out of interest, I tried the two scenarios whilst tracing the class 
loader. Yes in the case where the taskef is inside a target, the class gets 
loaded later. But since the initialisation of that task is done regardless, I 
cannot see this making a performance difference or memory difference. That is; 
unless your task spawns a new thread that is constantly churning.
