Work on all platforms. 2. Allow load and unload in arbitrary order and timings (which also means "be race free"). 3. Have low/zero overhead if not used Would you also require: 4. Have reasonable overhead when used a "must have" demand? Would, on the other hand, a: 4b. Have zero overhead when used for functions not hooked be an alternative demand? I'm currently trying to work with some other subscribers of this list on a design. Getting 1, 2 and 3 is a complicated enough task, of course. I would like to hear estimates about inclusion chances should we manage to come up with an implmentation that lives up to all the above.
