// This test assesses whether long-running writes can complete

|
// or timeout because the session or stream are not aware that the
|
|
// backing stream is still writing.
|
|
// To simulate a slow client, we write a really large chunk and
|
|
// then proceed through the following cycle:
|
|
// 1) Receive first 'data' event and record currently written size
|
|
// 2) Once we've read up to currently written size recorded above,
|
|
// we pause the stream and wait longer than the server timeout
|
|
// 3) Socket.prototype._onTimeout triggers and should confirm
|
|
// that the backing stream is still active and writing
|
|
// 4) Our timer fires, we resume the socket and start at 1)
