	// 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.
