misleading diagnostic printed on failure

[dankamongmen]

I'm seeing a lot of this with 1.2.37:

virtfs fuse.lxcfs at /proc/swaps
Couldn't read link at /sys/class/block/lxcfs (No such file or directory)
virtfs fuse.lxcfs at /proc/uptime
Couldn't read link at /sys/class/block/cgroup2 (No such file or directory)
virtfs cgroup2 at /sys/fs/cgroup
Couldn't read link at /sys/class/block/hugetlbfs (No such file or directory)
virtfs hugetlbfs at /dev/hugepages
Couldn't read link at /sys/class/block/mqueue (No such file or directory)
virtfs mqueue at /dev/mqueue
Couldn't read link at /sys/class/block/none (No such file or directory)
Error parsing /proc/swaps
Couldn't set up notcurses

and then a failure. weirdly enough, we also see Returning 0 though we're clearly not?

Killing the event thread...
Shutting down udev monitor...
Freeing devtable...
Closing libpci...
Returning 0...

nah, that's not why they're failing. they're failing because they can't initialize notcurses, which ought be fixed by my having inserted a TERM export just now.

why the returning 0, though?
