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.
