I've been looking at top(1) to try and get the CPU usage percentages to
come out better.  Upon looking at it, it seems that these values are
sucked straight out of the proc structure in the kernel, specifically
from the field p_pctcpu.  On my Integrated Solutions machine, this
value is kept as a fixed-point value in a long, rather than in a float
as is apparently done elsewhere.  "Top" looks at the value and then
scales it using a value defined elsewhere in proc.h, then prints the
result.  I took away the scaling to see the raw values from the kernel,
and they seem totally bogus.  Is this stuff supposed to work?
