Manik Surtani commented on JBCACHE-326:
---------------------------------------

I would have thought the concurrent stack would solve this.  Let's push this to 3.0.0 for now and most likely close it once we're closer to finishing with the 2.x.x series.

> Change the handling of requests in JBossCache (another  interceptor on top of ReplicationInterceptor): 
> - Create 2 queues (of MethodCall objects), one thread for each queue 
> - The regular MethodCalls like put(), remove() etc go into the  default queue (A), where they are processed according to order (FIFO) 
> - The special calls like block(), _getState(), commit() or acks  for PREPARE/COMMIT calls go into the other (priority) queue (B),  these calls *CAN* be received out of sequence 
> - This way, an _getState() would always be processed and  would be able to (1) stop the processing of queue A and (2) force- release any locks held 
>   by on the tree.
> _ This way commit() calls can promptly release locks, without having to wait behind other prepare calls.
