The collector reserves a 32GB zone of addresses to serve up scanned

It is only allocating addresses and not actually touching all of
that memory. Thus, it bumps the address space by 32GB, but does not
actually use 32 GB of memory or VM.
Thanks. I wish this was documented somewhere, preferably in Activity
Monitor's online help, because some people do notice the huge
allocation and freak out... I should file a bug on that.
