Basically, when something is allocated on the GC, the GC takes
full responsibility for managing its lifetime. User code should
not try to intervene. If your object needs to be managed
manually, don't allocate it from the GC, use C's malloc() or
your own memory allocation scheme. Because of this, class dtors
really should not be necessary if you only allocate objects
from the GC. They are only necessary when you need to manage
resources that are not allocated by the GC, such as OS file
handles, memory allocated by C's malloc(), or other such
things. The dtor should only take care of cleaning up these
external resources, and should not try to do anything related
to GC-allocated objects.

How does one go about determining if these are GC-allocated
objects, or if these are external to the GC?
