Implement CONDITION-WAIT and CONDITION-NOTIFY for ABCL.
That version of CONDITION-WAIT won't work properly:
Indeed it won't: thanks for the comments, and the kick in the butt.
After studying the needed abstractions in more detail I've [reimplemented most of the BORDEAUX-THREADS interfaces for ABCL based on the java.util.concurrent.ReentrantLock][1]. This code should now correctly implement the POSIX-style condition variables, the recursively held locks, and the form of lock acquisition that returns immediately.
Please consider the referenced patch for inclusion in BORDEAUX-THREADS.
