Hi, It sounds like this could be a good shim for flushHint(), as you said, if only on platforms where TCP_CORK is supported (Linux only?).

It's still more complex than just having a flushHint() method built in though, as it involves two modes (TCP_CORK and TCP_NODELAY).

Other platforms don't have it as simple; but you can accomplish similar things via manipulation of TCP_NODELAY on most systems. e.g. see http://stackoverflow.com/a/22118709/282536

Yeah. With enough jumping through hoops it's possible. What I am after is a nice, simple, logical API though.
