It's possible that Linux and Windows are using Python's malloc, whereas FreeBSD might be using the native PHK or JE malloc. (And it's not that surprising that different allocation patterns have different results in a garbage-collected environment.) http://docs.python.org/library/gc.html ...provides some info; consider importing gc and calling gc.collect() if you want to minimize the RAM needed to hold this big list of strings.
