----------------------------------

             Summary: Remote-executor threads should not block to acquire locks
                 Key: ISPN-5470
                 URL: https://issues.jboss.org/browse/ISPN-5470
             Project: Infinispan
          Issue Type: Task
          Components: Core
    Affects Versions: 7.2.1.Final
            Reporter: Dan Berindei
             Fix For: 8.0.0.Alpha1


Currently, enabling the queue on the remote-executor thread pool can cause deadlocks, because a CommitCommand/1PCPrepareCommand could end up in the queue while a remote-executor thread is busy waiting to acquire the same lock that this commit would release. 

If trying to acquire a lock would free the thread until the key has been acquired, we could enable the queue on the remote-executor/OOB thread pools, and we would need a lot less threads for the same load.
