Well, that requires to write platform specific code.
I would prefer to only use platform specific code when the platform provides something like pidfd: I understand that Linux, FreeBSD, OpenBSD, NetBSD, and Illumos are concerned. I mean reuse an exisiting solution, rather than writing our own "workaround" (solution?).
