Comment 23 for bug 1750013

Dan, this is the v3 of the patch. I bumped the version to 20.28 since my proposed 20.27 caused the regression aforementioned.

For this version, I removed the dependency of cgmanager, along with the code that added closing sessions to garbage collector. Happens that a similar code is present on systemd-logind already, and for some reason (which is still a mystery for me) I was seeing a session leak in the tool. My hypothesis is that I built one version of the tool without the bunch of debian patches, and so that portion of code wasn't present. Then, I started working in a fix, but in the end, the fix is useless since a similar one is already there.

Anyway, the patch now just avoid some small memory leaks in both session's free path and cgmanager glue code. It was tested in both kernels 3.13 and 4.14 (with and without cgmanager), I didn't observe leaks anymore nor high CPU utilization.

Thanks,

Guilherme
