Before we create a new context, we try and reap all the stale contexts (i.e. those that are freed but waiting for a worker to come and return their allocations to the system). Before we do this, we retire all requests so that we clear any inflight no longer used contexts (who are only being kept alived by those inflght requests). However, any context that is finally unreferenced by this retirement is put onto an RCU list and not available for immediately reaping, we stall for no immediate benefit.
