Reverts #1264. This was the likely cause of the outage this evening (#1277), there was an ongoing memory leak:
. The proximate cause was building the stm32 crates, which have a higher memory limit than normal and put us over the edge, but the server shouldn't have been resting at 10 GB RSS in the first place, it's usually much lower around 4 GB.
The site going down could have been avoided with #657. That would have delayed builds indefinitely, although it's possible we were leaking so much memory the site would still have eventually crashed.
