Bug 71690

The manpage for systat(1) is not accurate on what exacly is displayed
by the "vmstat" systat mode. It describes all the elements pretty well.
In the description of various virtual memory elements (like virtual/real
memory pages, active/inactive/wired pages etc.) it says that the numbers
displayed by systat are in page units. This is not true - the normal
page size is 4kB on an i386, and the numbers displayed are apparently
in kilobyte units (I have checked that on several machines, having say
100000 total real pages on a 128MB RAM machine is impossible; 
sysctl vm.vmtotal confirms that, comparing some numbers to the
top(1) output was also enlightening).

So, to make things clear, the manpage should state that the numbers
are not number of pages, but number of kilobytes in pages allocated
for something. It's also worth noting that not every 'number of pages'
in the display actually means 'number of kilobytes in pages'; it does not
affect page counts after 'daefr' or zero-fill page counts.

The display may be somewhat confusing, as the units (pages
and kilobytes) are mixed with each other and one has to remember
which counter has which units. But that's another issue..

Fix: That's my proposal, it isn't very elegant, but at least makes
it clear which counter are in pages, which in kilobytes.
