toWriteableBufferList

Returns a list of writeable blocks over the (source) content buffers.

This method returns the raw content of source buffers that may change over the lifetime of this object (blocks can be recycled or discarded, for example). Most applications should favor calling .toBufferList which returns a read-only view over the content of the source buffers.

The difference between .toBufferList and .toWriteableBufferList is that read-only view of source buffers will always return false from (which sometimes may be required to avoid double copying).
