We developed a very simple (even simpler than Kmonitor in that it didn't track fork/exec) way for a process to get notified when other processes exited (properly or otherwise). We want to use this in the field for a lifecycle monitoring function (a sort of super-init) so it needs to be as lightweight as possible. I'd love to be able to use something from the mainline kernel, but it has to be field-runnable without slowing stuff down.
