[sudo-workers] Re: closing all the file descriptors

[Todd C. Miller]

I have an implementation of this in the current sudo cvs tree.  The
option is now -C (close from) and it takes as an argument the fd
to start closing at.  There are two sudoers options:
 o closefrom specifies the default fd to start closing at

 o closefrom_override determines whether the -C option may be used
