I have a basic concept in this(multithreading and hash tables) subject both practically and theoretically. But I haven't worked on both at the same time so it would be a pretty good task. Looks like it will take around 2 months or so. [MT builds ran flawlessly with a running ./lisp.run executable but running ./clisp segfaults]

Which kind of hash table do you have in mind?
The best are usually preshing’s concurrent leapfrog http://preshing.com/20160314/leapfrog-probing/
or concurrent hopscotch.

Biggest problem besides weak hashes and the GC 
will be probing for the atomic intrinsics, and use slow locking or timestamps if not available.
