A nice interface to the finalizer functionality on different systems would Immanuel> be a great feature for cffi. How do you keep control over what foreign things point to the foreign objects? I've found that losing the last reference from Lisp is not usually a guarantee that the last reference is lost from the foreign side. Conversely, if you work around this by deliberately keeping a reference from Lisp to prevent the foreign object from being finalized, then you probably know exactly when it should be freed anyway. -- Martin Simmons Email: [EMAIL PROTECTED] LispWorks Ltd, St John's Innovation Centre TEL: +44 1223 421860 Cowley Road, Cambridge CB4 0WS, England.
