Following up with some discusson from a few months back,
where it was proposed that ProcessTable is a better name.
This data structure is definitely not a list ... if it
was one-dimensional it'd be a set, but in practice it has
much more in common with a two-dimensional table.
The Process table is a familiar operating system concept
for many people too so it resonates a little in that way
as well.
The "fscale" value, retrieved by sysctl() in BSD platforms, is used for
computing CPU percentages of the processes. To prevent a division by
zero, we should reject a zero "fscale" value. (A negative "fscale"
value will not make sense either.)
For DragonFlyBSD and FreeBSD, this would fall back to the hard-coded
default scale.
For NetBSD and OpenBSD, there is no hard-coded default value, so the
zero or negative "fscale" is now a fatal error.
