Review comment:
Hmm, it looks like we can drop `getSizeUnsafe()` method altogether, since it
doesn't differ from `getSize()` - both are not synchronized (also like
`setSize()`). It seems like I or @NicoK missed that when we were implementing
low latency changes and dropping the synchronisation in the `Buffer` class. Or
am I missing something?
