It's still too big, too slow [compared to gerbil] and uses a lot more memory. Gambit GC is amazingly fast, and never tenures garbage to a gen where it will collect like SBCL tends to do on many workloads. [acl/ccl/lw do not have this issue, although they are slower than sbcl]

What did you think would happen? Tolerating the remove of anyone's freedom should be fought. Even if they are not your bed fellows. Do nothing, and expect more of this to follow.
