If z/OS doesn't fit a traditional CS definition of a kernel, then what is it?
Does the BCP act as a micro or nano kernel with all other services sharing its
address space? Does the concept of "rings" or "kernel address space" even exist
on these machines?

I would venture to say that the operating system as we see it today is a
package of a kernel, API, and system utilities. Some would argue that an
operating system is only a kernel, and that wouldn't be wrong, just academic.

Absolutely! (Depending on the emulator and application, of course.)

How do we know the number of hardware design errors? With IA32, it's easier to
discover these problems because the CPU is used by many people under many
operating systems. IBM designs the OS and CPU, making it much easier to cover
up any problems that do exist.

Linux can have a small memory foot print. As far as I know, much of the size of
a kernel image comes from statically compiled modules. If space is a concern,
it's perfectly feasible to omit many kernel modules from the build process and
only keep those required as modules.
