To me, it could be implemented with one Gambas main program
and you SHELL or EXEC to your component Gambas programs.
Thus, they're only loaded when they run.
When they're done, they're freed.

Achieve unprecedented app performance and reliability
What every C/C++ and Fortran developer should know.
Learn how Intel has extended the reach of its next-generation tools
to help boost performance applications - inlcuding clusters.
