That, and 64-bit GC apps allocate a whopping 32 GB of VM on startup

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.
