Oh, and the kernel is an example, of course. Process management, memory
management, hardware drivers, multiple quite different kinds of IO and
some other stuff, all in a single monolithic whole. Completely the

aren’t terrible but let’s not pretend that the Unix kernel is an
examplar of the Unix philosophy l-)
