Log Message:
Implement mark & sweep garbage collection as suggested by Enami Tsugutomo
on "current-users" mailing list. Garbage collection is performed if:
1.) We previously allocated memory for the environment array which
is no longer used because the application overwrote "environ".
2.) We find a non-NULL pointer in the allocated environment array after
the end of the environment. This happens if the applications attempts
to clear the environment with something like "environ[0] = NULL;".
