General Tail Call Optimization?

I came across notes that indicate Neko has tail recursion
optimizations, but does it also support general tail call
optimizations? By this, I mean passing and calling closures
in tail
position frees stack space before allocating a new frame.

Yes, as soon as a call is made in tail position, the stack
is unwinded
before performing the call.

Sort of a related question: you've mentioned implementing
call/cc. 
What's the state of this?
