[find] dir fd not closed before/during exec

[Érsek László]

Hi,

I think starting_desc should be closed between the fork() and execvp()
calls in the child in find/pred.c/launch(). (Or FD_CLOEXEC should be set
on starting_desc somewhere before execvp(), maybe in find/find.c/main()?)

address@hidden:/tmp/lacos/findutils-4.1.20/find$ ./find -name . -exec sleep 100 
\; &
[1] 13757
address@hidden:/tmp/lacos/findutils-4.1.20/find$ ls -l /proc/$(pidof sleep)/fd
total 0
