netmgrd consuming a lot of memory on #238 on mako

[Alan Pope 🍺🐧🐱 🦄]

I updated my phone over the weekend and it's been on and idle on my desk for this time:-

 09:44:53 up 1 day, 23:35, 1 user, load average: 0.35, 1.23, 2.02

When I try to use it I get lockups and crashes. I spotted an OOM kill earlier, and it seems netmgrd is using a lot of RAM:-

Unfortunately not much we can do with this one, as it's a proprietary blob from qcom. Letting it open in case more users end up having the same issue.
