holdmysocks 4554502591 Tailscale for jailbroken PS5
A payload that runs the Tailscale client (tsnet, userspace networking) on a
jailbroken PS5: a C launcher built with ps5-payload-sdk that loads a Go
program in-process, an installer that registers it with the console's
payload autoloader and adds a home screen icon, and the patch that makes Go
1.27.1 speak the PS5's FreeBSD 9 era syscall interface.

/* List processes and kill stray test payloads.
