The org.jboss.threads.BlockingExecutor interface is deprecated in JBoss Threads 2 and removed in JBoss Threads 3.x, to which we want to move. Remove its use.

AFAICT all uses of this interface could just use plain old Executor from Java SE. They either simply call execute(Runnable) or they cast the instance to a subinterface and use methods from the subinterface.
