Wait, the last entry? If you're just printing out the values, then no --- those should have been garbage collected already.
Won't they be garbage collected only after the last entry is used, though?
No. A cell is generated once either (a) it, or (b) a cell earlier in the list, is required. A cell is garbage collected once both (a) it, and (b) all cells earlier in the list, are no longer required. So if you process the list strictly sequentially, it will be generated and garbage collected sequentially.
Since getDirectoryEntries returns a list, won't its elements have to be kept until the list is not used anymore, i.e., after the last entry is processed?
