Add pidfd support to GLib
This is a placeholder issue for thinking about how best to integrate the upcoming kernel pidfd support into GLib. It would be a Linux-only feature, so would have to be behind platform abstraction APIs. Current thinking:
- Use it widely in
GSubprocess
to identify the subprocess - Definitely use it for
g_subprocess_send_signal()
- Definitely use it for
g_subprocess_wait()
pidfd support is supposed to be complete in kernel 5.3, due out at the end of August 2019.
