It's not tying up a bunch of memory. It's using up some address space, but if it is indeed unused, the OS will not dedicate any actual RAM to that address space.
Andreas's initial message showed a pretty large difference in top's RES column -- wouldn't that indicate that that virtual address space is in fact backed by actual allocated physical pages?
It also showed that there was still 140MB free RAM out of a total of 390MB. There was no memory pressure to cause the OS to reclaim those pages.
Look at the big picture, not just a single detail.
