Fwiw, /bin/ps does this by creating it's own struct which has a
'struct kinfo_proc' as one variable inside of it.  However, this
means that `ps' has to copy all the kinfo_proc's that the kernel
returns into an array of these other structs.  Depending on what
the program is doing with those kinfo_proc's, this new variable
would probably make more sense.

It would be nice to make sure that alignment issues are not wasting
space on *any* of the platforms.  When I made my recent changes to
user.h, I had a program which printed out all the variables and
their alignments.  If I have time this week I will update that
program and see what it says on the different hardware platforms.
