What even is a pidfd anyway?

  It would be nice to see these APIs wrapped usably. Even something as basic as FreeBSD's similar `pdfork()` and `pdkill()` would go a long way. (`pidfd_send_signal` exists, but glibc does not provide an ergonomic wrapper. Nor is there an ergonomic wrapper around clone w/ CLONE_PIDFD.)

    Probably still up to date for most distros. That shows as being in the 6.9 tree only, but Ubuntu 24.04 just shipped with 6.8
