Feature Request: Support machines with 512MB RAM

[dogweather]

Describe the enhancement

It would be amazing if the runner would would on a Raspberry Pi Zero because these have enough computing power for many batch-type jobs and test scripts. They're also extremely energy efficient.

Additional information

Currently, the runner code (Linux ARM) crashes for configuration and run.sh. It's apparently out of memory. The runner, though, seems to use far less than 512MB RAM when actually running. I suspect there's something in the initialization code which temporarily uses a lot of RAM.

I have a similar/related issue. I have a small server that I want to auto-update but looking at my mem usage, my single runner is maintaining several instances and several copies of node.js
This is an issue as the test build also requires Opus to compile and since all the ram is being used, it can't even compile
