> Exchange worker is responsible for cache start/stop. With introduction of DD 
> and hence dynamic updates of cache types and indexes, it is necessary to 
> properly synchronize these operations wrt cache lifecycle.
> The most obvious way is to initiate these operations from within exchange 
> worker thread. In this case concurrent cache start/stop will always be 
> handled correctly.
> At the moment exhange manager is not ready for this. Need to perform some 
> refactoring to allow for optional tasks to be executed from that thread.
