When set, suexec will do a umask(2) system call before execve(2)ing your 
CGI. See "man 2 umask" for details, but the short version is that this 
sets the permissions on any file your CGI creates. (Your CGI can 
override this by calling umask(2) itself.) A reasonable value would be 
077, which means files will not be readable or writable by others. You 
might find more information on those numbers in the "man 2 chmod" or 
"man 1 chmod" manual pages.
