I understood "spawn" from this discussion to provide access to a CLI,
but what is valid from that point on certainly varies between
operating systems, and as I understand it, even between Unix
variants.  In general it would seem that portability of access
to "system" capabilities is not helpful between domains where
those capabilities are not identical.
