commit https://github.com/vim/vim/commit/81661fb86801e6d6e5194b43dfd27d73fcc016ec Author: Bram Moolenaar <Bram@vim.org> Date: Thu Feb 18 22:23:34 2016 +0100 patch 7.4.1351 Problem: When the port isn't opened yet when ch_open() is called it may fail instead of waiting for the specified time. Solution: Loop when select() succeeds but when connect() failed. Also use channel logging for jobs. Add ch_log().
