became_done is used to indicate whether to notify a counting barrier. We mostly 
need it if the regular mechanism won't work (e.g. we cancelled the exec rpc) or 
this is fire and forget. If IsDoneLocked() is true, then something else already 
signaled the barrier for this backend (e.g. UpdateBackendExecStatus when 
ApplyExecStatusReport sees that it is now done and returns true), so we 
shouldn't signal it here.
