-------------------------------------------------------------

I ran into this in a VM dev environment, and one way this can happen is due to a race with the use of {{Subprocess::ChildHook::SUPERVISOR}}. If {{perf}} is not installed, then the {{execv}} will fail, and this can happen before the supervisor parent process calls {{waitpid}}. Then {{waitpid}} returns -1 (with {{ESRCH}} and the supervisor calls {{abort()}}.
