So releasing the sleep inhibitor did not work properly so far, cause of forked fds.
That lead to suspend taking max delay seconds, which defaults to 5. (I used a
sleep 4 && hyprlock
to test that the system does not go sleep, so I did not notice.)As can be seen in my comments, for some reason we still need to explicitly close the fd in the child process despite setting O_CLOEXEC, which is weird.I removed the second fork cause we don't need it in hypridle, which also allowed to set SA_NOCLDWAIT and stuff which is nice to have for a daemon process.
