Hi,
calling s6-svunlink for a s6-svlink'ed service hangs with s6-2.12.0.0
and succeeds with previous s6-2.11.3.2
How to reproduce:
root@qemux86-64:~# cd /service
root@qemux86-64:/service# mkdir .n
root@qemux86-64:/service# echo -e '#!/bin/execlineb -p\nsleep 3000' > .n/run
root@qemux86-64:/service# chmod 755 .n/run
root@qemux86-64:/service# s6-svlink . .n n
root@qemux86-64:/service# s6-svstat n
up (pid 17882) 7 seconds
root@qemux86-64:/service# s6-svunlink . n
(Hangs in poll() and needs CTRL-C to exit)
root@qemux86-64:/service# s6-svunlink . n
root@qemux86-64:/service# echo $?
0
root@qemux86-64:/service#
Cheers
Christian
