If you don't treat glibc as a black box then you become
very vulnerable to being broken when details of its
implementation change. (Also it means you may no longer

Would it be possible to multiplex 64 by using sigqueue?
Just use si_value as the signal number when multiplexing.
Then you wouldn't have to keep taking away signal numbers
from runtimes and you break sigqueue for one signal number.
Just return an error and set EINVAL if a program calls sigaction

I was having trouble running golang on linux-user with an aarch64 target.
It turns out that snappy is written in Go. When I tried the xenial aarch64
preinstall image in qemu, Snappy was broken.
For some reason, it calls sigaction on all the signals.
I noticed do_sigaction in linux-user/signal.c
