I'm in favor of using wording something like what is used for "kernel 
oplocks" or one of the oplocks settings.  It basically says in the man 
page, "don't touch this unless you're sure you know what you're doing".  
Of course, everyone _always_ knows that they know what they're doing, so 
the effect may be somewhat limited.

There are still many guides out there that say to set socket options 
that these days would basically cripple your TCP/IP stack on Linux (and 
probably most other *NIXes).  People that like to "tune" will blindly 
drop these settings into their smb.conf regardless if the man page had a 
huge skull and cross bones with a mushroom cloud next to the option.
