Comment (by nickm):

 I've attached a separate patch from starlight on tor-relays (see "running
 Tor relay live with AddressSanitizer") that redirects stdout and stderr
 instead of closing them, and which uses `__sanitizer_sandbox_on_notify()`
 to work well with chroot and other sandboxen.

 This should be conditional on AddressSanitizer being enabled. Perhaps
 `__sanitizer_sandbox_on_notify()` also needs to be integrated with our
 seccomp2 sandboxing. Needs testing.
