// WINDOW_UPDATE is different than most other frames in that it can arrive
// while the client is still sending the request body.  In order to enforce
// this scenario, we feed a couple of dummy frames and give a delay of 0 to
// socket data provider, so that initial read that is done as soon as the
// stream is created, succeeds and schedules another read.  This way reads
// and writes are interleaved; after doing a full frame write, SpdyStream
// will break out of DoLoop and will read and process a WINDOW_UPDATE.
// Once our WINDOW_UPDATE is read, we cannot send SYN_REPLY right away
// since request has not been completely written, therefore we feed
// enough number of WINDOW_UPDATEs to finish the first read and cause a
// write, leading to a complete write of request body; after that we send
// a reply with a body, to cause a graceful shutdown.

// TODO(agayev): develop a socket data provider where both, reads and
// writes are ordered so that writing tests like these are easy and rewrite
