Note that there will be a lot more problems if we wanted to implement such an option. For example, if you wanted to be able to switch between an incremental and a conservative GC you would have to modify the vm itself so it properly tells the gc whenever a pointer is written (or accept a huge overhead). Therefore, I'd rather select boehm or kaffe at compile time and have -X options only for options specific to the selected implementation. Just because it will be easier. Why would one have to switch between kaffe and boehm at runtime, anyways?
