The profiler tried to be clever when handling process_exit events by subtracting one from the timestamp. This was supposed to ensure that events after a process' death would be attributed to the new process in case the old process used execve(). However, if there was another event (e.g. a CPU sample) at the exact same time the process_exit event was recorded the profile would fail to load because we didn't find the process anymore. This changes introduces a new problem where samples would be attributed to the incorrect process if a CPU sample for the old process, a process_exit as well as a process_create event plus another CPU sample event for the new process happened at the exact same time. I think it's a reasonable compromise though.
