^^^^ This link doesn't mean that it's pointing A but it's just
a trick to tell at the garbage collector that the sock A
has not to be shrunk in the hitlist.
I still think that calling it a tree is quite confusing. Maybe I didn't
understood the code completly though (I never looked into it before
this evening).
