Isn't there one more issue?  I'm not at all certain that a precise
collector would be more efficient.  With conservative GC you have to
scan the stack once per GC.  With precise GC, you have to do
bookkeeping (both registering and off-registering) for every single
SCM variable occuring on the stack between GC:s...
