GSoC multithreading project question

[Sergey V. <ser...@gm...>]

Hello,

My name is Sergey Vinokurov, I'm student from Ukraine and I would like to
work on thread safe lock-free hash tables. Project suggestion from official GNU
site mentions integration with garbage collector and in particular handling of
weak relations, and these weak relations make me doubt in my ability to finish
stated suggestion in full during summer due to my lack of experience with GCs.

So I'd like to ask, is it feasible to left handling of weak relations
as optional
and leave hash table implementation and basic GC integration as required? Or am
I just confused and weak relations can be added without much ado once
hash tables
are implemented and properly integrated with GC?
