Running 8 building 10 gives "Out of file descriptors" ?

[Dieter BSD]

By "fix this", I meant fix the brain dead error message from sh.

1 - The code should print the name of the program complaining.

2 - The code should print the errno string, and what caused the
error ( fcntl(F_DUPFD_CLOEXEC) ).

3 - The code should not stupidly print "Out of file descriptors",
since that might not be the problem.
