How does it help the GC?
As I understand the M&S algorithm, there's no real advantages in doing so.
In fact in many places to "null" references is considered to be an
anti pattern in java.

It seems like linkedList.clear() can be easily fixed to O(1) instead of
O(n).
The code is like that on purpose(!). It was done to help GC, in mustang
IIRC. There really isn't a problem with clear() being O(n) - it's going to
take at least O(n) to populate it, and in reality *many* times more cycles.
