podman-remote: kill -s: hangs

[edsantiago]

In window 1:

$ ./bin/podman system service --timeout=0

In window 2:

$ ./bin/podman pull fedora-minimal

$ ./bin/podman-remote run -d --name foo fedora-minimal env --default-signal sh -c "trap 'echo GOT HERE' 2;while :;do sleep 1;done"

$ time ./bin/podman-remote kill -s 2 foo
^C     <--- I got impatient before waiting 10 minutes
./bin/podman-remote kill -s 2 foo  0.12s user 0.09s system 0% cpu 8:34.25 total

$ ./bin/podman-remote logs foo
GOT HERE           <--- ok, so the signal DID make it to container

Using fedora-minimal and env because of #5004.

It also hangs with -s 3, which indicates that trap is not the problem. It also hangs with just plain sleep 999, I just did the trap thing so I could see if the container was getting the signal.

I'll take a stab at this one. Thanks for providing a reproducer, @edsantiago !

#7572 to the rescue
