Oh, I just saw that Perl is "violating POSIX" since Perl 1:
close-on-exec flag in set on new created file descriptors if their
number is greater than $SYSTEM_FD_MAX (which is usually 2).
I haven't checked the source, but I suspect this applies only to file
descriptors opened with open(), not to explicit POSIX::* calls. (The
documentation of the latter doesn't mention close-on-exec at all.)
Perl's open() contains functionality equivalent to Python's open() and
subprocess.Popen(), the latter of which already closes on exec by default.
