I mean using:

        ret = fcntl (fd, F_SETFD, FD_CLOEXEC);

so that programs which happen to call exec get their font files closed 
without forcing the application to know that underlying font files remain 
open.  As there's nothing useful to be gained from leaving them open, it 
seems sensible to simply make this call so that they are closed.

As 'exec' destroys the current VM environment, the face objects aren't 
"alive" after it's finished.
