That's an issue it's true. The other consideration if the program has 
to process a lot is that it's extremely inefficient of machine resources. 
All those processes starting up under the OS will gobble up CPU, so 
if your program is running on a shared computer then you could 
become very unpopular!

Long poipelines like that are really intended to be a user feature 
in Unix systems, putting them in batch files or long running 
processes - especially inside looops!! - is a very unfriendly 
thing to do. So be nice and use nice(1)....
