> when fork actions parallel submit will add ForkedActionStartXCommand and
> RecoveryService will check pending action may add ActionStartXCommand, if
> ForkedActionStartXCommand enqueue and there is a ActionStartXCommand(the same

> finish, but ForkedActionStartXCommand had lost and cause deadlock.

> Thread 1 and Thread 2 execute CallableWrapper's execute function order like:

> 2. Thread 2 execute queue add ActionStartXCommand into queue and add to

> 3. Thread 1 execute queue add ForkedActionStartXCommand into queue, but
> filterDuplicates() function found a same name XCommand in uniqueCallables, so
> skip add to queue;
> Becasue ForkedActionStartXCommand and ActionStartXCommand has the same name,
> Thread 2 add ActionStartXCommand enqueue before Thread 1, so
> ForkedActionStartXCommand would be lost(never execute), and the thread that
