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.
