Seems reasonable. I'll push this.

No, the test also does 'open ("/dev/null",...)', which _does_ require the
open module.

Subject: [PATCH] test-dup2: reduce dependencies
dup2 is fully if the cloexec module is in use, but dragging in
cloexec just to test whether an fd is valid was a bit much.
* modules/cloexec (Configure.ac): Set witness.
* modules/dup2-tests (Depends-on): Drop cloexec.
* tests/test-dup2.c (main): Skip portion of test if cloexec module
not present.
Suggested by Bruno Haible.
