This project amounts to "Implement Your Own Operating System," because
it requires that the DBMS take over the things that operating systems
normally do, like:
a) Managing access to filesystems and
b) Managing memory
The world is already sufficiently filled up with numerous variations
of Linux, BSD 4.4 Lite, and UNIX System V; I can't see justification for
reinventing this wheel still again.
