I suppose, it will be able to eat all available system memory (was > killed). Do resource limits apply to root? I wonder if it's an issue of calculation in top; top might be including page sizes and other VM-related things, while limits datasize and stacksize may only be specific to those allocated amounts. If this machine was running RELENG_7 (STABLE), it would have procstat, which could help discern where the "extra" memory is.
