Please see the full report text in this upstream issue: https://phab.enlightenment.org/T7486

The fix is trivial -- add O_CLOEXEC to an open.  I thought upstream might fix it, but it does not appear they will.  So we might consider patching it in ports.

The patch to fix is totally trivial:

Fyi, this was addressed upstream:
