Don't be fooled by things though.

FreeBSD also assigns a VSIZE value but only allocates this when the
application really needs it.  In other words, should you add up the
VSIZEs and other SIZEs the result could be very skewed in that it won't
measure up to your memory and swap partition sizes.

I need to fix the sourcecode first before I can even compile it on BSD
again. =P
