Like the procdesc system on FreeBSD, which has some rather unfortunate semantics though. (Closing last open descriptors kills processes, by default.) One could make a collection of bugs that are revealed by (quite normal) process ID re-use. One of particular note in this context is the bug that occurs when one is using Linux control groups in lieu of proper job objects (which Linux does not have) and trying to do what on an actual first-class job object would be a "terminate all processes in this job" system call. * http://jdebp.uk./FGA/linux-control-groups-are-not-jobs.html http://jdebp.uk./FGA/linux-control-groups-are-not-jobs.html * https://github.com/systemd/systemd/issues/6803 https://github.com/systemd/systemd/issues/6803
