Review comment:
Can you add a test coverage for this? It might be quite east to add
`assertTrue(buffer.isRecycled()` assertion(s) at the end of
`SingleInputGateTest#testBasicGetNextLogic()`:
1. maybe manually checking that buffer created by
`inputChannels[0].readEndOfPartitionEvent();` was recycled or ...
2. ...
a. recycle non event buffers in `verifyBufferOrEvent(...)`
b. and add general assertion to `TestInputChannel` whether all buffers were
recycled?
