That, and 64-bit GC apps allocate a whopping 32 GB of VM on startup on Leopard, which might scare a few people that (1) watch Activity Monitor like a hawk, and (2) think that VM == swap. Most people won't notice, though.
It actually isn't 32GB Of VM, even. The collector reserves 32GB of contiguous addresses, which shows up as VM in Activity Monitor. None of the pages are touched, though, so it is -- as you note -- completely innocuous.
But hard to explain, which is a well understood problem and steps have been taken to improve the situation.
