 One way that I've implemented this in the past is to make a status
 pipe.  If the exec fails, we write `errno' as a single byte to the
 pipe from the child.  We also mark the write end close-on-exec, so if
 the exec succeeds the parent sees the pipe close without any data
 being written.
 
 Not sure why I didn't just implement it when I wrote the code.
