We clean up the descriptors in "pdes" in call cases, so we're not leaking kernel resources. You're right that "iop" (and "cur", which you didn't mention) appear to be leaked in the child, in that they're not explicitly cleaned up. But they get wiped away by the _execve(), so it doesn't matter.

See my next reply. I care not about userland resources, but about
fdopen() ability to set FD_CLOEXEC.
