Actually, procstat doesn't provide the functionality which 
pmap_helper.ko or exmap does, although it is still a useful tool to have.

I unfortunately don't have time to look at sysutils/pmap or do further 
work on exmap at this moment, which is why I'm asking people for help as 
they may also benefit from the tool.

Thanks for the feedback!
