For non-trivial confinement, constructor == parent.  For trivial confinement,
there is no constructor.

In case of trivial confinement, the idea is to have some pages of code, and
make a system call on them to turn them into a process.  In that case,
instantiator == parent.

This is non-trivial (non-)confinement.
