[ section 9 manual pages on trunk but not release ]
   
   Its too late for 1.2 [ ... ]

why must it be too late for 1.2 ?  aren't documentation fixes
(and in this case, additions) not problem for incorporation
right upto the last minute ?  espcially since these are new
manuals and have useful information in them, that the users
and developers of netbsd applications need.
