It sets the maximum amount of memory that may be wired (i.e. marked as
unswappable).  Unfortunately, this is a rather fuzzy concept in FreeBSD,
as it includes memory wired by userland applications using mlock(2), the
unified buffer cache, and (if I'm not mistaken) memory wired by device
drivers for DMA buffers and the like.  There should be separate limits
for all of these, and per-process limits for the first.  Patches are
welcome :)
