           * The Buffer constructor returns instances of `Uint8Array` that are augmented
           * with function properties for all the node `Buffer` API functions. We use
           * `Uint8Array` so that square bracket notation works as expected -- it returns
           * a single octet.
           *
           * By augmenting the instances, we can avoid modifying the `Uint8Array`
           * prototype.

          // a transform stream is a readable/writable stream where you do
          // something with the data.  Sometimes it's called a "filter",
          // but that's not a great name for it, since that implies a thing where
          // some bits pass through, and others are simply ignored.  (That would
          // be a valid example of a transform, of course.)
          //
          // While the output is causally related to the input, it's not a
          // necessarily symmetric or synchronous transformation.  For example,
          // a zlib stream might take multiple plain-text writes(), and then
          // emit a single compressed chunk some time in the future.
          //
          // Here's how this works:
          //
          // The Transform stream has all the aspects of the readable and writable
          // stream classes.  When you write(chunk), that calls _write(chunk,cb)
          // internally, and returns false if there's a lot of pending writes
          // buffered up.  When you call read(), that calls _read(n) until
          // there's enough pending readable data buffered up.
          //
          // In a transform stream, the written data is placed in a buffer.  When
          // _read(n) is called, it transforms the queued up data, calling the
          // buffered _write cb's as it consumes chunks.  If consuming a single
          // written chunk would result in multiple output chunks, then the first
          // outputted bit calls the readcb, and subsequent chunks just go into
          // the read buffer, and will cause it to emit 'readable' if necessary.
          //
          // This way, back-pressure is actually determined by the reading side,
          // since _read has to be called to start processing a new chunk.  However,
          // a pathological inflate type of transform can cause excessive buffering
          // here.  For example, imagine a stream where every byte of input is
          // interpreted as an integer from 0-255, and then results in that many
          // bytes of output.  Writing the 4 bytes {ff,ff,ff,ff} would result in
          // 1kb of data being output.  In this case, you could write a very small
          // amount of input, and end up with a very large amount of output.  In
          // such a pathological inflating mechanism, there'd be no way to tell
          // the system to stop doing the transform.  A single 4MB write could
          // cause the system to run out of memory.
          //
          // However, even in such a pathological case, only a single written chunk
          // would be consumed, and then the rest would wait (un-transformed) until
          // the results of the previous transformed chunk were consumed.
