OK, I'm curious; how _would_ one go about testing this?
Generate a really big data structure in memory.  fork().  sleep for a bit 
so you can see how much memory is used.  Now in one of the processes, 
change all the data.  sleep some more so you have time to see how much 
memory is used.

Not very elegant, I'll admit ;-)
