If the remote handler is blocked on a send, and the client is trying to send without the remote receiving,
the operation would become deadlocked if the channels are full.

### Typed handlers

Typed handlers are handlers that have a specific type for the request and response payloads.

```go
    // Create a typed handler.

			m.o[i].metadata = nil
		}
	}
	m.o = m.o[idx:]
}

// mergeEntryChannels will merge entries from in and return them sorted on out.
// To signify no more results are on an input channel, close it.
// The output channel will be closed when all inputs are emptied.
// If file names are equal, compareMeta is called to select which one to choose.
// The entry not chosen will be discarded.

		t.staleUploadsCleanupInterval = cfg.StaleUploadsCleanupInterval

		select {
		case staleUploadsCleanupIntervalChangedCh <- struct{}{}:
		default: // in case the channel is blocked...
