Here. I posted comments in this thread and in a similar thread about
such systems. They are generally all variations on mark and sweep
collection. The more efficient ones use colouring.

I don't buy either of these difficulties since I have worked with and
implemented systems which have full garbage collection and have no
problems interfacing to C, or dealing with resources like files. These
are all arguments against *some* garbage collection schemes, but not
all.
