That is what led me to assume that O_CLOEXEC might be defined as zero
when our kfreebsd-images are built (and hence FD_CLOEXEC set by
default). But I can't easily check this until I get a new kfreebsd-*
build environment set up.
This would explain why the problem only occurred in a jail on a FreeBSD
upstream kernel (which presumably doesn't do this, because their own
libc has the ability to set FD_CLOEXEC later on an open fd if requested).
