The sanitizer still complains about it (just checked a new emacs build
from master branch), but we have at least figured out a way to disable
the sanitizer [1], so IMO the bug can be closed.

For the record ~10 different packages out of around 2000 has triggered
this file descriptor sanitizer (that I've seen so far), and in most
cases it has been as unclear as for emacs what the issue is/if there
actually is an issue.
