Yes, looks normal and expected from what you observed.  mmap commits
memory top-down and that was apparently the first free slot big enough
to fullfil the request.  The default heap size is 384 Megs and then
there's apparently not enough space anywhere.  Keep in mind that a
request of 674Mib is a third of the available VM on 32 bit machines.
So, drop the heapsize and go with it, or use the -M option.
