According on [link](https://github.com/apple/foundationdb/blob/0e4a6cc92101fdaf008e68f662316f52836f0c58/fdbserver/TLogServer.actor.cpp#L375), it seems that memory for this `TLogQueue` is never released, is this a memory leak?  
And also this [one](https://github.com/apple/foundationdb/blob/0e4a6cc92101fdaf008e68f662316f52836f0c58/fdbserver/worker.actor.cpp#L1500).

This is handled in `tlogTerminated` which you can find [here](https://github.com/apple/foundationdb/blob/0e4a6cc92101fdaf008e68f662316f52836f0c58/fdbserver/TLogServer.actor.cpp#L3077). The only way the `tlog` actor ever can exit is through a transaction. `tlogTerminated` will check whether the tlog was removed (in which case it will dispose it) or whether it exits for another reason (in which case it will close the queue).
