From c2000651a200530ba08161207ade5eea8bbeec43 Mon Sep 17 00:00:00 2001 From: Richard Purdie Date: Mon, 24 Dec 2018 16:32:18 +0000 Subject: process: Handle EWOULDBLOCK in socket connect Now that we set a timeout for the socket, it can return EWOULDBLOCK if a signal or other event happens to wake up even if we don't timeout. If this happens, retry the connection, else we simply see it quickly loop through the retries and abort the connection in a very short interval.
