If I understand right, the linking part of what you suggest should
not only be possible but easy, since constructors and destructors are
already handled similarly. They put pointers to themselves in special
sections (.ctor, .dtor), which djgpp.lnk and some code in crt0 handle
specially. ".lock" would want entire functions and every variable they
touched.
