Are you certain that the function does away with all references, so 
that the GC can really remove the data before the function is called 
again?

If the function uses global variables, you're at risk of leaving 
"static" data around, that can only be collected after you run the 
function *again*, to point those variables at new data. This can 
cause a function to keep two generations of data alive at all times, 
even though it's only really using one.
