This is a project simply provides a metaclass which when used means that you do not have to manually
manage locks. This package exports one thing metalock which is a metaclass for use with whatever
class definitions you want. This metaclass is implemented using *-using-class methods so your
distribution of CL must use these methods to implement access functions like 'slot-value' for this metaclass to work. Obviously it must also implement the MOP. I have tested on SBCL 1.4.9 only.
Access to slots is controlled using read-writer locks described here: https://en.wikipedia.org/wiki/Readers%E2%80%93writer_lock#Using_a_condition_variable_and_a_mutex
(defclass myclass ()
((oneslot :accessor oneslot :initform 1))
(:metaclass metalock:metalock))Instantiate and use like normal.

- needs to work for initialized instances when you redefine the class.
