      // 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.
