The condition variable interface is using the mutex lock specified in BT:CONDITION-WAIT.  For the ABCL implementation, I'm using the Java monitor associated with the condition variable for the additional synchronization needed to implement BT:CONDITION-NOTIFY which couldn't use the mutex lock without contention problems.  But definitely check my logic here, as it has been faulty before.

If we are implementing posix-style-semantics, we could avoid reinventing that wheel on java, and use http://download.oracle.com/javase/1.5.0/docs/api/java/util/concurrent/locks/... which has the posix semantics.
