Linker, can you spare a meg? (2021)
Tailscale on iOS runs as a special kind of app, a Network Extension. This lets us run in the background, so we can secure traffic from all of your applications, without them having to change anything. But with this power comes a memory straightjacket. Normal iOS apps can use 5GB or so of memory before iOS kills them…
