GD has a garbage-collection library and module, which exports a
GC-gcollect method that forces full garbage collection. In the
not-yet-implemented section are the methods GC-register-finalizer and
GC-invoke-finalizers. It should be easy to implement them, they are
wrappers around Boehm gc functions of the same name, the only trick is
the conversion of a Dylan function to a function pointer.

GC-general-register-disappearing-link is the name of the function for
that. Also not implemented yet.
