Please consider the [following patch for ABCL against BORDEAUX-THREAD
HEAD][1]. The patch provides implementation of both BT locking
semantics (recursively head and not) by use of
[java.util.concurrent.locks ReentrantLock][2] as well as a (hopefully)
correct implementation of POSIX-style condition variable, and allows
non-blocking lock acquisition.
