```
std.ChildProcess: bypass libc exit() in fork child error case

Comment reproduced here:

If we're linking libc, some naughty applications may have
registered atexit handlers which we really do not want to
run in the fork child. I caught LLVM doing this and it
caused a deadlock instead of doing an exit syscall. In
the words of Avril Lavigne, "Why'd you have to go and
make things so complicated?"

```
