Review Comment:
Just to be clear: The original reason to have a ThreadLocal was to do not
allocate one byte[] per row, which is expensive. Allocating one byte[] per
segment is totally fine. We allocate quite more than that in other parts of the
same path. And usually it is a bad thing to be too aggressive at catching in a
managed environment like the JVM
