I now understand why name caching was redone for 4.4BSD; Net/2's

Browse Source 
method of caching names has a totally bogus interface.  kill *ALL*
caching of names when going through a lofs, because that's the only
way to make sure things always work right.  Also, XXX the possibly-bogus
check i keep whining about.  it's almost certainly wrong, but it's
too weird to modify significantly; even jsp didn't want to touch it...
