| After digging for hours why something like
| FOO_PASS_FD=3 exec /usr/pkg/bin/foo 3</path/to/pass
| worked on -6, but not on -8, I found out that redir.c:1.38 introduced
| setting close-on-exec for redirections, 1.40 tried to fix it, but probably
| not for the command being exec'ed being exec.
| At least 1.55 made it conditional on !posix, so I have a workaround.
I will look at it, see if there's some simple solution, but there
is (or should be) another workaround
3<&3
should turn off close on exec, so
FOO_PASS_FD=3 exec something 3</whatever 3<&3
should work.
