> potentially block this stage again since many methods are synchronized in
> ActiveRepairService.
> Methods prepareForRepair(could block for 1 hour for prepare message response)
> and finishParentSession(this one block for anticompaction to finish) are
> synchronized and could hold on to the lock for a long time.
> In RepairMessageVerbHandler.doVerb, if there is an exception for another
> repair, removeParentRepairSession(also synchronized) will block.
