12311    -1 // a transform stream is a readable/writable stream where you do
12312    -1 // something with the data.  Sometimes it's called a "filter",
12313    -1 // but that's not a great name for it, since that implies a thing where
12314    -1 // some bits pass through, and others are simply ignored.  (That would
12315    -1 // be a valid example of a transform, of course.)
12316    -1 //
12317    -1 // While the output is causally related to the input, it's not a
12318    -1 // necessarily symmetric or synchronous transformation.  For example,
12319    -1 // a zlib stream might take multiple plain-text writes(), and then
12320    -1 // emit a single compressed chunk some time in the future.
12321    -1 //
12322    -1 // Here's how this works:
12323    -1 //
12324    -1 // The Transform stream has all the aspects of the readable and writable
12325    -1 // stream classes.  When you write(chunk), that calls _write(chunk,cb)
12326    -1 // internally, and returns false if there's a lot of pending writes
12327    -1 // buffered up.  When you call read(), that calls _read(n) until
12328    -1 // there's enough pending readable data buffered up.
12329    -1 //
12330    -1 // In a transform stream, the written data is placed in a buffer.  When
12331    -1 // _read(n) is called, it transforms the queued up data, calling the
12332    -1 // buffered _write cb's as it consumes chunks.  If consuming a single
12333    -1 // written chunk would result in multiple output chunks, then the first
12334    -1 // outputted bit calls the readcb, and subsequent chunks just go into
12335    -1 // the read buffer, and will cause it to emit 'readable' if necessary.
12336    -1 //
12337    -1 // This way, back-pressure is actually determined by the reading side,
12338    -1 // since _read has to be called to start processing a new chunk.  However,
12339    -1 // a pathological inflate type of transform can cause excessive buffering
12340    -1 // here.  For example, imagine a stream where every byte of input is
12341    -1 // interpreted as an integer from 0-255, and then results in that many
12342    -1 // bytes of output.  Writing the 4 bytes {ff,ff,ff,ff} would result in
12343    -1 // 1kb of data being output.  In this case, you could write a very small
12344    -1 // amount of input, and end up with a very large amount of output.  In
12345    -1 // such a pathological inflating mechanism, there'd be no way to tell
12346    -1 // the system to stop doing the transform.  A single 4MB write could
12347    -1 // cause the system to run out of memory.
12348    -1 //
12349    -1 // However, even in such a pathological case, only a single written chunk
12350    -1 // would be consumed, and then the rest would wait (un-transformed) until
12351    -1 // the results of the previous transformed chunk were consumed.
