Do you mean tracking the pointers conservatively is easy or tracking
them precisely is easy?  To do this precisely, wouldn't you have to
know the pointee's type?  Would this information be provided by
a method stored in the virtual function table of the pointee?  Then,
wouldn't this exclude classes without virtual functions?  Alternately,
it could be stored in something like Boehm's gc_descr which is stored
with the pointee.  Is that what you mean.  But wouldn't this require
somehow defining gc_descr for each type with has dynamically allocated
instances?
