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.
