commit https://github.com/vim/vim/commit/107e1eef1df3b786ad3ad49fbdb9e058649303b5 Author: Bram Moolenaar <Bram@vim.org> Date: Fri Apr 8 17:07:19 2016 +0200 patch 7.4.1719 Problem: Leaking memory when there is a cycle involving a job and a partial. Solution: Add a copyID to job and channel. Set references in items referred by them. Go through all jobs and channels to find unreferenced items. Also, decrement reference counts when garbage collecting.
