Dimitri John Ledkov 82fbd3f55c osdep/unix/exec: Avoid atexit() handlers when child execvp() fails ... The functions grub_util_exec_pipe() and grub_util_exec_pipe_stderr() currently call execvp(). If the call fails for any reason, the child currently calls exit(127). This in turn executes the parents atexit() handlers from the forked child, and then the same handlers are called again from parent. This is usually not desired, and can lead to deadlocks, and undesired behavior. So, change the exit() calls to _exit() calls to avoid calling atexit() handlers from child.
