The wrapper is a setuid-root program, and thus potentially very dangerous.
To minimize that danger, it should do one thing and one thing only: set the
UID/GID that the rest of the code is going to operate under. It should be
as simple as it can possibly be. Figuring out the current load in a C
program is decidedly NOT simple...
