Peter Schuller commented on CASSANDRA-3838:
-------------------------------------------

So given that for keep alive that would involve potential non-portable code and
such, let's keep that for later unless someone is willing to actually write
that keep-alive patch in a timely fashion.
{quote}
I have nothing against that at all, to be clear. I didn't mean to sound like I
was arguing against this going in. I am very much for it, +1. In fact I'd
rather have this just be turned on by default (with a reasonably high default
timeout) than having FD convictions kill streams. So no argument here.
Timeouts like these can be exchanged for keep-alive:s in the future without
really affecting the surrounding logic, if that feature becomes available.
