thread:make-cond-var &optional name &key auto-free[Function]

Make a new condition variable encapsulating a pthread condition variable. When auto-free is t, the pthread structure will be automatically freed when the lisp object is no longer accessible, and reallocated when lisp is restarted. When auto-free is :note, the condition variable is noted and reallocated upon restart but is not automatically freed.
